That means a single 20-VFQFN part replaces up to four discrete quartz oscillators, cutting BOM line count and board area.
Runs on any rail from 2.25 V to 3.6 V, so it works with 2.5 V or 3.3 V supplies without an extra regulator.
Product status is Active per Microchip's lifecycle record.
Housed in a 20-VFQFN with exposed pad (5.00 mm × 3.20 mm footprint, 0.90 mm height).
Yes — this is a MEMS-based XO (Standard), not a quartz crystal. It provides the same clock function with better frequency stability (±50 ppm) over temperature and vibration. It is a drop-in replacement for a quartz oscillator in the same 20-VFQFN footprint, but check the output type (LVCMOS or LVDS) matches your receiver.
It supports both LVCMOS and LVDS outputs. The four outputs can be configured independently — the 12 MHz and three 50 MHz rails each can be set to either standard, giving you mixed single-ended and differential clocks from one device.
