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 framesync 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.
