DS21610
3.3V/5V Clock Rate Adapter
www.maxim-ic.com
GENERAL DESCRIPTION
The DS21610 is a multirate, low-jitter clock adapter
that converts E-carrier and T-carrier clocks to
multiple PDH carrier clock rates. Two clock outputs
are available that are frequency-locked to the input
clock. The clock outputs along with an 8kHz frame-
sync output can be phase-aligned to a frame-sync
input. The device is backward compatible with the
LXP610 and operates from either a 3.3V or 5V
supply. All modes of operation include a standard
8kHz output.
