Operating from 2.25V to 3.6V, this oscillator spans the 2.5V and 3.3V logic rails common in mixed-voltage designs — no separate LDO needed when the core and I/O voltages differ. The 6-VDFN Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm, a standard footprint that routes easily on two-layer boards; the exposed pad improves thermal transfer to the PCB ground plane.
It is a 41.5 MHz XO with CMOS output — a standard square-wave clock signal that interfaces directly with most MCUs, FPGAs, and logic without external level translation.
The DSC1121 series is manufactured as RoHS-compliant and lead-free per Microchip's standard material declaration. Confirm the specific date code compliance with your order.
Yes, the Enable/Disable pin allows gating the output. When disabled, the maximum supply current drops from 35 mA to 22 mA — not a full shutdown, but a useful power reduction for idle clock domains.
