Dual-frequency MEMS XO for audio/video clock trees
The DSC400-0101Q0082KE2 is a MEMS-based XO (Standard) oscillator from Microchip's DSC400 series, delivering two independent LVCMOS outputs at 22.5792 MHz and 24.576 MHz — the exact frequencies needed for audio sample-rate clocks and video pixel clocks in HDMI or SDI interfaces.
Supply voltage and enable control
Operates from a single 2.25V to 3.6V supply, so it runs directly off a 2.5V or 3.3V rail without an external LDO — the Enable/Disable pin lets a host processor gate the outputs for power sequencing or sleep modes.
Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm body, 0.90 mm height), the thermal pad must be soldered to a ground plane for mechanical stability and thermal relief — the pad also serves as the primary heat path in still air.
