Dual-frequency LVDS clock for high-speed serial links
The DSC2033FI1-F0026T is a MEMS-based XO (Standard) oscillator from Microchip's DSC2033 series, delivering two LVDS clock outputs: 400 MHz on output 1 and 200 MHz on output 2. This dual-frequency capability makes it a direct fit for FPGA reference clocks, SerDes transceivers, and high-speed data converters that require a clean differential clock at two distinct rates from a single device. The LVDS output swings a differential signal with low jitter. The enable/disable function lets the system gate the clock without a separate buffer.
Industrial temperature grade and MEMS reliability
The MEMS resonator inside is inherently more shock- and vibration-tolerant than a quartz crystal — a practical advantage for equipment mounted on a machine tool or in a vehicle cab. Frequency stability is ±50 ppm across the full temperature and supply range, which holds the clock edge within a tight window for a high-speed SerDes or ADC reference.
Package footprint and board integration
Housed in a 14-VFQFN exposed pad package measuring 3.20 mm x 2.50 mm with a 0.90 mm height, the DSC2033FI1-F0026T occupies a compact footprint on the PCB. Supplied in tape and reel (TR), the part is ready for automated pick-and-place assembly. The enable/disable function is active-low; tying the pin high or leaving it floating enables the output, while pulling it low disables the LVDS driver and drops the supply current to 23 mA max.
