MEMS-based quad-output clock for broadcast video and Ethernet
The DSC400-3333Q0099KE2T is a four-output MEMS-based XO (Standard) from Microchip's DSC400 series, delivering LVDS clock signals at 148.35/148.5 MHz, 156.25 MHz, 208.333333 MHz, and 197.8/198 MHz — frequencies that align with broadcast video frame rates (148.5 MHz for 1080p/60) and Ethernet line rates (156.25 MHz for 10G/25G SerDes reference). The 20-VFQFN exposed pad package (5.00 mm x 3.20 mm, 0.90 mm height) and 2.25 V to 3.6 V supply range let it sit on a mixed-voltage board without a separate regulator — the LVDS outputs swing to the rail, so the common-mode voltage tracks the supply.
