Description
7-
Reserved.
6
PG_CK
This bit selects the reference clock when the pattern (including PRBS, ARB & IB) is generated.
When the pattern is generated in the receive path:
0: XCLK. (default)
1: Recovered clock from the received signal.
When the pattern is generated in the transmit path:
0: XCLK. (default)
1: Transmit clock, i.e., the clock input on TCLKn (in Transmit Single Rail NRZ Format mode and in Transmit Dual Rail NRZ For-
mat mode) or the clock recovered from the data input on TDPn and TDNn (in Transmit Dual Rail RZ Format mode)
5 - 4
PG_EN[1:0]
These bits select the pattern to be generated.
00: Disable. (default)
01: PRBS.
10: ARB.
11: IB.
3
PG_POS
This bit selects the pattern (including PRBS, ARB & IB) generation direction.
0: Transmit path. (default)
1: Receive path.
2
PAG_INV
This bit controls whether to invert the generated PRBS/ARB pattern.
0: Normal. (default)
1: Invert.
1 - 0
PRBG_SEL[1:0] These bits are valid only when the PRBS pattern is generated. They select the PRBS pattern.
00: 220 - 1 QRSS. (default)
01: 215 - 1 PRBS.
1X: 211 - 1 PRBS.
