SerialLite II Protocol Reference Manual

SerialLite II Specification

Signal Definitions

Table 2–1 provides a list of the interface signals, including a short

description of their functionality.

Interface Diagrams

The SerialLite II protocol supports an interface that recovers the clock and

data for a serial bit.

Figure 2–4 shows the SerialLite II protocol in asynchronous mode, where

the clock and data is recovered from the serial bit stream, and each device

has its own reference clock.

Figure 2–4. Asynchronous Clock & Data Recovery

Figure 2–5 on page 2–14 shows the SerialLite II protocol in synchronous

mode, where the clock and data is recovered from the serial bit stream,

and the reference clock is shared between devices.

TD[0-N]

Output Transmit data—Carries payload data and in-band

control words. TD connects to RD of the receiving

device.

RD[0-N]

Input Receive data—Carries payload and in-band control

words. RD connects to TD of the transmitting

device.
