MEMS clock source with dual LVDS outputs
The DSC400-3333Q0089KI2T is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering two LVDS clock outputs at 148.35 MHz and 148.5 MHz.
Industrial temperature grade and stability
For a 10GbE link running at 148.5 MHz, ±25 ppm keeps the bit-error rate within the PHY's capture range without external VCXO trimming.
Housed in a 20-VFQFN exposed pad package measuring 5.00 mm x 3.20 mm, the part requires a thermal via array under the pad for heat sinking. The 0.90 mm height keeps it compatible with standard 1.6 mm PCB stack-ups.
Sourced through independent distribution; quantities confirmed at RFQ.
