The DSC1101AI2-156.2500T is a MEMS-based XO (standard oscillator) delivering a 156.25 MHz CMOS output — the reference frequency for 10G Ethernet, Fibre Channel, and many FPGA transceiver banks.
Seated height is 0.90 mm max.
95 µA max supply current in standby (power-down) mode. This is the current drawn when the output is disabled — the oscillator core is off, but the bias and control logic remain powered.
MEMS oscillators (like the DSC1101) have no moving quartz blank — they are inherently more shock- and vibration-tolerant than quartz-based XOs. The trade-off is typically slightly higher phase noise at close-in offsets. For 156.25 MHz CMOS clocking of an Ethernet PHY or FPGA, the MEMS reliability advantage usually outweighs the noise difference.
