Dual-frequency clock in a 14-VFQFN package
The DSC2042FI2-M0005T is a MEMS-based XO (Standard) that delivers two independent output frequencies: 156.25 MHz on output 1 and 25 MHz on output 2, selectable between HCSL and LVPECL logic families. Housed in a 14-VFQFN Exposed Pad package measuring 3.20 mm x 2.50 mm with a 0.90 mm profile, it fits tight board stacks where a single oscillator replaces two cans.
Expect it in outdoor telecom cabinets, factory-floor PLCs, and engine-bay control modules where ambient heat cycles are the norm.
Current consumption and disable mode
Maximum supply current is 76 mA typical when both outputs are active — the dual-frequency architecture draws about what a single high-speed XO would, thanks to the MEMS resonator core. That is the quiescent draw of the internal bias circuits; the outputs are tri-stated, so the downstream logic sees no clock edge.
