3.3V/5V Clock Rate Adapter

The DS21600/DS21602/DS21604 are multiple-rate clock adapters that convert between E-Carrier and T-Carrier clocks rates. A T1 or E1 clock output, CLKOUT1, is available, along with a higher multiple rate clock output, CLKOUT2. CLKOUT1 and CLKOUT2 are frequency locked to the clock input CLKIN. The clock outputs, along with frame-sync output, can be phase-aligned to a frame-sync input. The devices are fully compatible with the LXP600A, LXP602, and LXP604, and operate from either a 5V or 3.3V supply. All operation modes include a standard 8kHz output.

The DS21600/DS21602/DS21604 are available in 16-pin SO, and are rated for industrial temperatures.
