Dual-frequency MEMS XO for audio/video clock trees
The DSC400-0101Q0083KE2T is a MEMS-based XO (Standard) that generates two independent LVCMOS clock outputs: 45.1584 MHz on Output 1 and 49.152 MHz on Output 3. These frequencies are the standard audio sample-rate references — 45.1584 MHz serves 44.1 kHz-family audio (CD, DAT), while 49.152 MHz covers 48 kHz-family audio (AES/EBU, Dolby Digital) and common video pixel clocks. A single oscillator replaces two cans on the board, saving footprint and BOM line count.
Supply range, stability, and enable function
Operates from a wide 2.25 V to 3.6 V supply rail, covering 2.5 V and 3.3 V logic domains without an extra regulator.
Package, footprint, and sourcing posture
Housed in a 20-VFQFN exposed-pad package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm.
