Output is LVPECL (Low-Voltage Positive Emitter-Coupled Logic), a differential signal standard that requires 50-ohm termination to Vcc-2V. The 148.3516 MHz frequency fits high-speed serial protocols like Gigabit Ethernet, PCIe reference clocks, or FPGA transceiver banks that need a clean differential clock. That's tight enough for a 10/100/1000 Ethernet PHY or a wireless base station where the clock jitter budget is single-digit picoseconds. Supply voltage spans 2.25V to 3.6V, so it runs directly off a 2.5V or 3.3V rail without an extra LDO. Housed in a 6-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The 0.197\" x 0.126\" footprint is a standard MEMS oscillator land pattern — compatible with many quartz oscillator pads, so a board designed for a 5x3.2 mm can often drop this part without a layout change. Product status is Active per Microchip's lifecycle records.","metaTitle":"DSC1122BI5-148.3516T MEMS XO, LVPECL, 148.3516 MHz, ±10 ppm","metaDescription":"Microchip DSC1122BI5-148.3516T: MEMS-based XO, LVPECL output, 148.3516 MHz, ±10 ppm stability, industrial temp range.
