SLLSEE1 – MAY 2013

The TLK10232 provides two pins: PRBSEN and PRBS_PASS, for additional control and monitoring of

PRBS pattern generation and verification. When PRBSEN is asserted high, the internal PRBS generator

and verifier circuits are enabled on both transmit and receive data paths on high speed and low speed

sides of all channels. PRBS 27-1 is selected by default, and can be changed through MDIO.

When PRBS test is enabled (PRBSEN=1):

•

PRBS_PASS = 1 indicates that PRBS pattern reception is error free.

•

PRBS_PASS = 0 indicates that a PRBS error is detected. The channel, the side (high speed or low

speed), and the lane (for low speed side) that this signal refers to is chosen through MDIO.

3.18 10GBASE-KR Latency

The latency through the TLK10232 in 10GBASE-KR mode is as shown in Figure 3-5. Note that the latency

ranges shown indicate static rather than dynamic latency variance, i.e., the range of possible latencies

when the serial link is initially established. During normal operation, the latency through the device is fixed.
