This frequency suits Ethernet PHY reference clocks, MCU system clocks, and FPGA configuration oscillators that require a stable 41.5 MHz source without a quartz crystal's aging drift.
The supply voltage range spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V logic rails.
Housed in a 6-VDFN package with an exposed pad (7.00 mm x 5.00 mm, 0.90 mm seated height), the DSC1121AI2-041.5000 requires a thermal pad on the PCB for heat sinking.
The output frequency is 41.5 MHz. This is a fixed-frequency oscillator; no frequency programming or divider adjustment is available on this order code.
