DS3112 Clock Rates and Frequency Tolerances of the Transmit Clock

Abstract: The DS3112 has six different transmit clock and six different receive clock types: transmit DS3, DS2,DS1, E3, E2, and E1 clocks and receive DS3, DS2, DS1, E3, E2, and E1 clocks. Since the clocks at thesame stage in the circuit have similar characteristics the clocks will be described in pairs as DS3(E3), DS2(E2) and DS1(E1). This application note clarifies the frequency tolerances of the transmit clock, transmit and receive clock-rate capabilities, and the DS1/E1 transmit and receive clock interface details.
