The DSC1203CE2-167M7722T is a MEMS-based XO delivering a 167.7722 MHz LVDS output with ±25 ppm frequency stability across -20°C to +70°C — a drop-in clock source for Ethernet, FPGA reference, or SerDes PLLs that need a low-jitter differential signal. Supply voltage spans 2.5V to 3.3V, so the same oscillator can feed a 2.5V FPGA bank and a 3.3V PHY without a separate level translator.

Frequently asked questions
What is the standby (power down) function of DSC1203CE2-167M7722T?
The standby function disables the oscillator and reduces the supply current to 5 µA max. The output goes high-impedance when standby is asserted.
Is DSC1203CE2-167M7722T RoHS compliant?
The part is supplied in a Tape & Reel package; Microchip's standard RoHS compliance applies. Confirm the specific date-code lot at RFQ.
