Selecting an Oscillator Crystal
Specific crystal parameters are required for
proper operation of the jitter attenuator. It is rec-
ommended that
Transmit Side Jitter Attenuation
In some applications it is desirable to attenuate
jitter from the signal to be transmitted. A
CS61577 in local loopback mode can be used as a
jitter attenuator. The inputs to the jitter attenuator
are TPOS, TNEG, TCLK. The outputs from the
jitter attenuator are RPOS, RNEG and RCLK.
Line Protection
Secondary protection components can be added
to provide lightning surge and AC power-cross
immunity. Refer to the "Telecom Line Protection
Application Note" for detailed information on the
different electrical safety standards and specific
application circuit recommendations.
