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.
