The DSC1001CL1-033.3330T is a MEMS-based oscillator (XO) from Microchip's DSC1001 series, delivering a fixed 33.333 MHz CMOS output.
The supply voltage range spans 1.8V to 3.3V, so the same oscillator works across a 3.3V microcontroller and a 1.8V FPGA bank without a level translator. Active current draw is 7.2 mA max at full speed, and frequency stability is ±50 ppm over the -40 to 105°C industrial temperature range — tight enough for CAN and Ethernet clocking without external trimming.
Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The lands are on the bottom — no through-holes, so the oscillator sits flat on the PCB.
