The DSC1121BI2-050.0000 is a 50 MHz MEMS-based oscillator from Microchip's DSC1121 series, delivering a CMOS output in a 6-SMD no-lead package (5.00mm x 3.20mm footprint).
Supply flexibility and frequency stability
The supply range spans 2.25V to 3.6V, so it runs directly off a 2.5V or 3.3V rail — no extra LDO needed. At 50 MHz the max supply current is 35 mA; pulling the enable pin low drops it to 22 mA. Frequency stability is ±25 ppm, tight enough for a 100BASE-TX Ethernet reference or a high-speed ADC clock without external trimming.
