MEMS oscillator with dual audio/video clock outputs
The DSC400-0101Q0082KE1T is a MEMS-based XO (Standard) that generates two fixed LVCMOS frequencies: 22.5792 MHz and 24.576 MHz — the standard audio and video reference clocks for HDMI, S/PDIF, and Ethernet PHY timing. It operates from a single 2.25 V to 3.6 V supply, so it can run off either a 2.5 V or 3.3 V rail without an extra LDO.
Package and layout for the 20-VFQFN
The 20-VFQFN exposed pad measures 5.00 mm x 3.20 mm with a 0.90 mm height — the pad must be soldered to a ground plane with thermal vias to keep junction temperature within the -20°C to +70°C operating range.
