Clocking
The source clock for the transmit data path is selectable from
either the recovered clock or an external BITS (Building
Integrated Timing Source) reference clock. The low jitter of the
CDR PLL enables loop timed operation of the transmit data path
meeting all Bellcore and ITU jitter requirements.

Multiple loopback and loop through modes are available for both
diagnostic and normal operation. For systems containing
redundant SONET rings that are maintained in standby, the
CYS25G0101DX may also be dynamically powered down to
conserve system power.
