Product details

MEMS oscillators typically offer better shock and vibration resistance, shorter lead times, and no quartz supply-chain constraints. The 156.25 MHz output is a standard frequency for 10GbE and Fibre Channel reference clocks, so this part fits directly into a SERDES PLL input without a separate multiplier.

Temperature grade and supply range

Package and mounting – 6-SMD no-lead

Housed in a 5.00mm x 3.20mm x 0.90mm 6-SMD no-lead package – the land pattern matches standard 6-pin oscillator footprints, so it drops in as a drop-in replacement for quartz XOs of the same size.

Frequently asked questions

Can DSC1121BI2-156.2500T replace a standard quartz crystal oscillator?

Yes – the 6-SMD no-lead footprint and CMOS output are pin-compatible with many standard quartz XOs of the same package size. The MEMS resonator offers better shock/vibration tolerance and typically shorter lead times. Confirm the output load (CMOS) and supply voltage range (2.25V–3.6V) match your design.
