DS21600/DS21602/DS21604 3.3V/5V Clock Rate Adapter is a multi-rate clock adapter from Maxim IC that converts between E-carrier and T-carrier clock rates.
The Maxim DS21600, DS21602, and DS21604 are multiple‑rate clock adapters that convert between E‑carrier and T‑carrier clock rates. They provide a T1/E1 clock output (CLKOUT1) and a higher‑multiple clock output (CLKOUT2), both frequency‑locked to the input clock (CLKIN). An 8 kHz SYNCOUT is always available and can be phase‑aligned to a frame‑sync input.
The devices are offered in 16‑pin SO and 8‑pin DIP packages, operate from a 3.3 V or 5 V supply, and are rated for industrial temperature ranges. Detailed pin descriptions, functional operation, jitter performance, timing parameters, and package information are included.
| Frequency Conversion (example) | CLKIN 1.544 MHz → CLKOUT1 2.048 MHz → CLKOUT2 6.144 MHz |

They operate from either a 3.3 V or a 5 V supply.
The SO package has 16 pins.
