Product details

Frequency stability is ±25 ppm across the full temperature range, which keeps the 65 MHz clock within 1.6 kHz of nominal — sufficient for 1 GbE reference clocks and most FPGA transceiver PLLs.

Supply voltage tolerance and power budget

6-SMD no-lead package — board-fit note

The 3.20 mm x 2.50 mm x 0.90 mm 6-SMD no-lead package is a standard footprint — the 0.126" x 0.098" land pattern matches the common 3.2 x 2.5 mm oscillator pad layout. No via-in-pad required; the exposed centre pad (if present) should be connected to ground plane with a single via to avoid solder wicking.

Frequently asked questions

Is the DSC1122CI2-065.0000 compatible with a 3.3 V supply?

The internal regulator handles the variance without an external LDO.

Can the DSC1122CI2-065.0000 replace a quartz oscillator at 65 MHz?

Functionally yes — it is a drop-in MEMS replacement for a 65 MHz quartz XO with LVPECL output. The MEMS base resonator offers better shock and vibration tolerance (no quartz crystal to crack) and faster start-up, typically under 5 ms. Verify the supply voltage range and output type match your design.
