The DSC1123DI2-155.5200T: This is a MEMS-based XO (Standard) oscillator delivering a 155.52 MHz LVDS output — the exact frequency used in 10GbE and many SerDes reference clocks. The LVDS differential pair gives clean edge rates over short board traces, reducing EMI compared to a single-ended CMOS oscillator at this frequency.
AEC-Q100 qualification and active production status
Sourced through independent distribution; confirmed availability and pricing at RFQ.
Supply voltage flexibility and enable/disable function
Operates from 2.25V to 3.63V, covering both 2.5V and 3.3V rails without an intermediate regulator — one less part on the BOM.
Housed in a 6-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The small footprint fits tight layouts near the processor or PHY. Surface-mount reflow assembly; no through-hole or socket — plan for pick-and-place.
