Active MEMS XO for broadcast video clocking
The DSC400-3333Q0089KE2T is an active-production Microchip MEMS XO delivering two LVDS clock outputs at 148.35 MHz and 148.5 MHz — the exact pixel rates for 1080p59.94 and 1080p60 video standards. It is a drop-in timing source for professional broadcast cameras, video switchers, and SDI transmission gear that needs both frame rates on the same board.
Runs from 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an extra regulator. For a 148.5 MHz clock, that is a maximum drift of ±3.7 kHz — well within the capture range of a downstream PLL in a video decoder or FPGA transceiver.
Package and board layout notes
20-VFQFN with exposed pad, 5.00 mm × 3.20 mm body, 0.90 mm height. The 0.50 mm pitch QFN demands a solder-paste stencil aperture that matches the land pattern; a 4-mil stencil is typical.
