Receiver

Jitter
PLL is designed to accommodate large amounts of input jitter with high power supply rejection for operation in
noisy environments. PLL has a minimum input jitter tolerance exceeding all requirements shown in Figure 3. The
measured receiver jitter tolerance for DS1 and CEPT operation is also shown in Figure 3, with pseudorandom input
data (2
15
– 1) and with EXCLK synchronous with the data source. The receiver transfers incoming jitter to RCLK
with no more than 2 dB of gain at any frequency, which can be further reduced with the jitter attenuator.
