144.08 MHz MEMS XO — why the ±10 ppm and CMOS output matter
The DSC1121BE5-144.0800 is a MEMS-based XO (Standard) that outputs a 144.08 MHz CMOS clock with ±10 ppm frequency stability — tighter than the ±25 ppm typical of a quartz oscillator at the same frequency, which buys you margin in Ethernet, SerDes, or RF reference clock jitter budgets.
6-VDFN package — board layout fit
The 6-VDFN package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a low-profile surface-mount footprint that fits under shielding cans or on tight back-side PCB real estate.
