The simplest method of transferring data through the inputs or outputs of a silicon chip is to directly connect the datapath from one chip to the next chip.

Since data often consist of more than one bit of information , the datapath is more than one-bit wide.

There are two inherent problems of the parallel data bus. The second problem involves meeting timing requirements. Due to these two problems we thought about transforming parallel data to serial stream of data to be able to use serial communications off-chips and on- chips.

The transmitter serializes communication systems, so the choice of SerDes can have a parallel data, equalizes it and then drives the serial data onto a big impact on system cost and performance. While the maze of differential signal pair of interconnect wires. A basic understanding of these architectural upon the sample point established by the CDR.

In this paper we examine four channels are called simplex cores; Serdes cores which contain distinct SerDes architectures and show how each plays a vital both transmit and receive channels are called full duplex cores. Any given electrical interconnect channel has a fixed direction of data transmission.

The high-speed clock in the Serdes is divided down to generate a sample clock for the parallel data. Because the phase of this clock is determined by the internal state of the serializer, the Serdes channel generally provides this clock as an output for use by logic driving data to the transmit channel. Conceptually, the deserializer receive block performs the inverse function of the serializer block. Serial data is deserialized onto an n-bit databus of similar width to the Fig.

A sample clock is generated by dividing down the The differential driver stage is an analog circuit which internal high-speed clock, and this clock is supplied as an drives the true and complement legs of the differential signal. In a similar Output data must be driven such that jitter is minimized. Differential Receiver: B. Many variations on filter architectures are possible, all of which accomplish this. This equalizer distorts the signal at the transmitter output such that the resulting signal at the receiver input is a clean waveform.

Parallel Clock SerDes: Fig. Clock and Data Recovery CDR : CDR circuits monitor transitions of the data signal and select an optimal sampling phase for the data at the mid-point between edges. Since the timing of data transitions includes a jitter component, the CDR must perform some averaging to provide stability of this sampling point from one bit to the next.

Inter symbol interference ISI and other components of deterministic jitter DJ are dependent on the spectral content of the data signal, and this frequency spectrum does change based on the data content. Shifts in this frequency spectrum sustained for hundreds of bits or more cause the CDR to adjust the optimal sampling phase dynamically. The resulting serial automatic receiver lock to random data.

This is an especially data streams travel to the receiver in parallel with an additional useful feature in systems where the receiver is in a remote clock signal pair that the receiver uses to latch in and recover module not under direct system control and also in systems the data. Since clock and data travel on multiple pairs, pair-to- where one transmitter broadcasts to multiple receivers. In the pair skew must be minimized for proper deserialization. Common parallel bus Embedded clock bits SerDes are well suited to non-byte- widths for these chipsets include , , and bits.

The bit transmission codes were developed by Fig. Two multiple edge transitions every cycle as well as DC balance clock bits, one low and one high, are embedded into the serial balanced number of transmitted ones and zeros.

DC balance facilitates driving creating a periodic rising edge in the serial stream. Data AC-coupled loads, long cables and optical modules. After powering up, the receiver automatically searches for the periodic embedded clock rising edge. Once locked, the receiver recovers boundaries in the serial stream, the transmitter first marks one data from the serial stream regardless of payload data pattern.

This is an especially useful feature in systems marker for receiver code alignment. Once code alignment is where the receiver is in a remote module not under direct accomplished, the receiver maps the bit codes back to byte system control. Since the receiver is locked to the incoming data, flagging an error if it detects an invalid 10b code.

As a result, they typically require tight Embedded clock bits SerDes are especially well suited to external clock source frequency and jitter control. For Ottawa, Canada.

While this scheme does not count total bit errors, it is a good way to monitor serial link performance. Bit Interleaving SerDes: Fig. The receiver demultiplexes the bits back into the original slower streams. Note that a serial stream coming into transmitter input channel 1 may not come out on receiver output channel 1. This is not regarded as a problem in the applications because the serial streams contain independent cell or packet data that is processed downstream.

In this thesis various line driver topologies were analysed to identify a topology suited for a high-speed low-voltage operating environment. This thesis starts of by introducing a relatively new high-speed communication Device called SerDes. SerDes is used in wired chip-to-chip communications and operates by converting a parallel data stream in a serial data stream that can be then transmitted at a higher bit rate, existing SerDes devices operate up to A matching SerDes device at the destination will then convert the serial data stream back into a parallel data stream to be read by the destination ASIC. SerDes typically uses a line driver with a differential output. Using a differential line driver increases the resilience to outside sources of noise and reduces the amount of EM radiation produced by transmission.

The material focuses on HSS devices, and the consolidation of related topics into a single text. Chip and system designers using HSS devices must have detailed knowledge of both the features and functions of the HSS device, and the applications in which they are used. Also designers must have a working knowledge of related subjects, including: reference clock architectures, signal integrity, power dissipation, and test features and functions. The authors consolidate these topics with a specific focus on HSS devices. This approach provides the chip designer sufficient background information for using HSS devices on their chips. The chapters can be viewed as four distinct sections.

High speed serial link design (SERDES) Introduction, Architectures and applications

These blocks convert data between serial data and parallel interfaces in each direction. The term "SerDes" generically refers to interfaces used in various technologies and applications. It may use an internal or external phase-locked loop PLL to multiply the incoming parallel clock up to the serial frequency. The simplest form of the PISO has a single shift register that receives the parallel data once per parallel clock, and shifts it out at the higher serial clock rate. Implementations may also make use of a double-buffered register to avoid metastability when transferring data between clock domains.

Несмотря на субботу, в этом не было ничего необычного; Стратмор, который просил шифровальщиков отдыхать по субботам, сам работал, кажется, 365 дней в году. В одном Чатрукьян был абсолютно уверен: если шеф узнает, что в лаборатории систем безопасности никого нет, это будет стоить молодому сотруднику места. Чатрукьян посмотрел на телефонный аппарат и подумал, не позвонить ли этому парню: в лаборатории действовало неписаное правило, по которому сотрудники должны прикрывать друг друга. В шифровалке они считались людьми второго сорта и не очень-то ладили с местной элитой. Ни для кого не было секретом, что всем в этом многомиллиардном курятнике управляли шифровальщики.

 - Хочу его запатентовать. - Как торговую марку? - Беккер смотрел на него изумленно. Парень был озадачен. - Для имени нужна торговая марка, а не патент. - А мне без разницы.  - Панк не понимал, к чему клонит Беккер. Пестрое сборище пьяных и накачавшихся наркотиками молодых людей разразилось истерическим хохотом.
