MEMS-based dual-frequency clock source
The DSC400-0101Q0083KI2T is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering two fixed LVCMOS output frequencies: 45.1584 MHz and 49.152 MHz.
Supply voltage and output control
Operates from a 2.25 V to 3.6 V supply — compatible with 2.5 V and 3.3 V logic rails without a separate level translator. The LVCMOS output swings rail-to-rail, so it drives standard CMOS inputs directly.
20-VFQFN package and layout considerations
Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm body, 0.90 mm height). The 0.50 mm pitch QFN footprint requires a solder stencil aperture reduction of 10-15% to avoid bridging — standard for this package class.
Microchip lists the DSC400-0101Q0083KI2T as Active.
