Overview
Byte Ordering
Each channel carries an STS-12 worth of data. The ordering of bytes within the STS-12 is shown in Table 14. In
the case of an STS-192, each of the STS-12 channels comprising the STS-192 carries an STS-12 extracted from
the STS-192. The byte ordering in this case is shown in Table 15. STS-48 ordering follows the same format, with
each constituent STS-12 of the STS-48 entering the chip on separate channels.

Receive Interface
Receiver Operations
The receiver is composed of 48 STS-12 channels that are either treated as independent channels, treated as three
groups of 16 channels each, forming three STS-192 streams, or treated as 16 groups of three channels each,
forming 12 STS-48 streams. Incoming data for each channel is received through an LVDS serial port operating at
622 Mbits/s. The incoming serial stream frequency must be the same as the outgoing LVDS serial stream of the
transmitter. Each STS-192 interface (16 channels) uses the system clock (SYS_CLK) as a reference clock.
The receiver is able to handle STS-12 streams having combined static and dynamic frame offsets of up to 64 bytes
without creating any traffic disruption.
