MEMS oscillator with LVPECL output at 74 MHz
The DSC1122CE5-074.0000 is a standard MEMS-based XO (Standard) from Microchip's DSC1122 series, delivering a 74 MHz LVPECL differential output. LVPECL is the output type here — it's a differential signal that requires 100-ohm termination at the receiver, typical for high-speed clock distribution in networking or FPGA reference clocks. Frequency stability is specified at ±10 ppm, which keeps the jitter contribution low enough for most 1 GbE and 10 GbE PHY reference clock applications. The supply voltage range spans 2.25V to 3.6V, so it can run from a 2.5V or 3.3V rail without an external regulator.
Sourced through independent distribution; quantities confirmed at RFQ.
6-SMD footprint and commercial temperature grade
The 6-SMD, No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard MEMS oscillator footprint that is pin-compatible with many other 6-pin oscillators from SiTime, Epson, and IDT.
