What this MEMS oscillator delivers — and what it no longer is
The 2.50 mm × 2.00 mm 4-SMD no-lead package (0.90 mm seated height) fits tight PCB layouts where a quartz can-style oscillator would consume too much board area.
Microchip lists this part as Obsolete. For existing designs that already carry this oscillator, the last-time-buy window has closed. No stock-holding claim — availability is verified per order.
Why MEMS over quartz for this frequency
At 12.288 MHz, this oscillator is a natural fit for audio clocking (48 kHz sample-rate families), USB full-speed, or as a reference for a PLL multiplying to common Ethernet or serial data rates.
