Product details

MEMS-based 68 MHz LVPECL oscillator for industrial clocking

Output is LVPECL — a differential, low-voltage positive emitter-coupled logic standard — which means this oscillator drives high-speed serial interfaces (Gigabit Ethernet, PCIe, SATA) directly without an external level translator.

Supply voltage range and power budget

Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails common in FPGA and SoC designs — no extra regulator needed if the rail is within that window.

Housed in a 6-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts without requiring a dedicated oscillator footprint area. Surface-mount mounting with no leads simplifies reflow soldering and inspection; the small 6-pin package is compatible with standard pick-and-place equipment.

Product status is Active per Microchip's lifecycle designation — no EOL notice, no last-time-buy window.

Frequently asked questions

Can DSC1122CI5-068.0000 replace a standard 68 MHz quartz oscillator?

The MEMS resonator offers better shock and vibration tolerance than quartz, and the ±10 ppm stability matches or exceeds many quartz XOs. However, it is not pin-compatible with a single-ended LVCMOS quartz oscillator — the output type and footprint differ. Check that your receiver accepts LVPECL levels before substituting.

What is the output type and voltage supply for DSC1122CI5-068.0000?

Output is LVPECL (differential). Supply voltage range is 2.25 V to 3.6 V.
