Product details

MEMS clock source for industrial timing

The DSC1121BI5-022.5792 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a 22.5792 MHz CMOS output from a 2.25V to 3.6V supply rail.

Supply voltage and frequency tolerance

With an absolute pull range of ±10 ppm, the output frequency stays within tight bounds across the full 2.25V to 3.6V supply range and temperature sweep — no external load capacitors or trim resistors needed. The 6-VDFN package (5.00mm x 3.20mm, 0.90mm seated height) is a standard footprint for MEMS oscillators; the 0.197" x 0.126" body matches many quartz XO layouts, simplifying board swap.

Frequently asked questions

How do I enable/disable the output on DSC1121BI5-022.5792?

The Enable/Disable pin controls the output: pull high for active output, pull low to disable (output goes high-Z). Disabled current drops to 22 mA max from 35 mA max.
