212.5 MHz LVDS clock for high-speed serial links
The DSC1123DL5-212.5000: This is a 212.5 MHz LVDS oscillator from Microchip's DSC1123 MEMS family — the frequency and output type put it squarely in the timing chain for 10G Ethernet PHYs, FPGA transceiver reference clocks, and SerDes framer devices that need a low-jitter differential clock. The LVDS output swings 350 mV typical into a 100-Ω differential termination, which keeps radiated emissions lower than a single-ended CMOS clock at this frequency — a real advantage when routing a 212.5 MHz trace across a multi-layer board.
MEMS resonator vs quartz — the survivability edge
MEMS oscillators handle shock and vibration better than quartz — a known failure point in automotive and industrial environments where a quartz blank can crack or frequency-pull under mechanical stress. For a 212.5 MHz clock, ±10 ppm translates to ±2.125 kHz of total frequency error, well within the capture range of a typical SerDes CDR.
AEC-Q100 grade — under-hood temperature band
Supply voltage range is 2.25V to 3.63V — it runs from a 2.5V or 3.3V rail without a separate LDO, and the wide tolerance covers rail droop during transients.
