DESCRIPTION
The DS21600, DS21602, and DS21604 are multiple-rate clock adapters that convert between E-carrier
and T-carrier clocks rates. These devices are available in 16-pin SO and are rated for industrial
temperatures. A T1 or E1 clock output is available, CLKOUT1, along with a higher multiple rate,
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 a single 5V supply. All
operation modes include a standard 8kHz output.
Note:
Some revisions of this device may incorporate deviations from published specifications known as errata. Multiple
revisions of any device may be simultaneously available through various sales channels. For information about device errata,
