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.
