9.16.1 Receive Data Interface

9.16.1.1 Receive Pattern Detection

The Receive BERT receives only the payload data and synchronizes the receive pattern generator to the incoming

pattern. The receive pattern generator is a 32-bit shift register that shifts data from the least significant bit (LSB) or

bit 1 to the most significant bit (MSB) or bit 32. The input to bit 1 is the feedback. For a PRBS pattern (generating

polynomial xn + xy + 1), the feedback is an XOR of bit n and bit y. For a repetitive pattern (length n), the feedback is

bit n. The values for n and y are individually programmable (1 to 32). The output of the receive pattern generator is

the feedback. If QRSS is enabled, the feedback is an XOR of bits 17 and 20, and the output is forced to one if the

next 14 bits are all zeros. QRSS is programmable (on or off). For PRBS and QRSS patterns, the feedback is

forced to one if bits 1 through 31 are all zeros. Depending on the type of pattern programmed, pattern detection

performs either PRBS synchronization or repetitive pattern synchronization.

9.16.1.2 PRBS Synchronization

PRBS synchronization synchronizes the receive pattern generator to the incoming PRBS or QRSS pattern. The

receive pattern generator is synchronized by loading 32 data stream bits into the receive pattern generator, and

then checking the next 32 data stream bits. Synchronization is achieved if all 32 bits match the incoming pattern. If

at least is incoming bits in the current 64-bit window do not match the receive pattern generator, automatic pattern

resynchronization is initiated. Automatic pattern resynchronization can be disabled.
