72 MHz MEMS clock for industrial timing
The DSC1121DL5-072.0000 is a MEMS-based standard oscillator (XO) delivering a 72 MHz CMOS output — a common clock rate for 100BASE-T Ethernet PHYs, USB 2.0 full-speed controllers, and high-performance MCUs that need a clean reference without a quartz crystal's startup delay.
Supply flexibility and frequency stability
Operating from 2.25V to 3.6V, this oscillator runs directly off a 2.5V or 3.3V rail without an extra LDO — the wide Vdd range simplifies power-tree design and reduces BOM count. The ±10 ppm absolute pull range (APR) holds the output frequency tighter than many quartz-based XOs; for a 72 MHz serial link, that translates to lower bit-error rate over temperature and voltage.
Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this oscillator occupies minimal PCB area — suitable for space-constrained designs like IoT modules or compact industrial sensors. Surface-mount assembly with a standard 6-pin VDFN footprint; the enable/disable function is on a dedicated pin, so no external pull-up or pull-down resistor is needed for the output-enable logic.
