MEMS clock for industrial and audio timing
The DSC1121AI5-022.5792T is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 22.5792 MHz CMOS output — a frequency used in audio sampling clocks (44.1 kHz multiples) and video frame-rate references. The 6-VDFN exposed-pad package (7.00 mm × 5.00 mm, 0.90 mm seated height) suits surface-mount assembly on a 2-layer board — the exposed pad needs a thermal via pattern to the ground plane for heat sinking.
Frequency stability is ±10 ppm absolute pull range (APR) — tight enough for Ethernet clocking or an audio master clock without external trimming.
