2.3 Jitter Attenuator

The Jitter Attenuator (JAT), illustrated in Figure 2-8, attenuates jitter in the

receive or transmit path, but not both simultaneously. In the receive configuration,

the line signal is recovered by the RLIU and is dejittered before it is decoded by

the RCVR. In the transmit configuration, the encoded signal from the transmit

block is dejittered before it is transmitted by the Transmit Line Interface Unit

(TLIU). The JAT receive/transmit configuration is done through the JDIR bit in

the Jitter Attenuator Configuration register [JAT_CR; addr 002]. The JAT can also

be completely disabled using the Jitter Attenuation (JEN) bit in the JAT_CR
