GENERAL DESCRIPTION

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.
