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. * Direct Replacement for LXP610SE * Converts E-Carrier Clock Rates to T-Carrier Clock Rates * Converts T-Carrier Clock Rates to E-Carrier Clock Rates * 3.3V or 5V Supply * Low Jitter Output * Multiple Output Clocks Synchronized to Input Clock * 8kHz Frequency-Locked Output for all Operation Modes * No External Components Required * 16-Pin SO and 28-Pin PLCC * Industrial Temperature Range: -40ºC to +85ºC
