• Manufacturer Part Number: pi2eqx5804d
• Description: 5.0gbps 4-lane Pcie? 2.0 Redrivertm With Equalization & Emphasis
• Manufacturer: Pericom Semiconductor Corporation

Equalizer
Notes
K28.7 pattern is applied differentially at point A as shown in AC test circuit (see figure).
Total jitter does not include the signal source jitter. Total jitter (TJ) = (14.1 × RJ + DJ) where RJ is random RMS jitter and DJ is maximum deterministic jitter.
Signal source is a K28.5 ± pattern (00 1111 1010 11 0000 0101) for the deterministic jitter test and K28.7 (0011111000) or equivalent for random jitter test.
Residual jitter is that which remains after equalizing media-induced losses of the environment of Figure 1 or its equivalent. The deterministic jitter at point
B must be from media-induced loss, and not from clock source modulation. Jitter is measured at 0V at point C of the AC test circuit (see figure).
