Product details

MEMS clock source with three fixed-frequency lanes

The 20-VFQFN exposed-pad package (5.00 mm x 3.20 mm, 0.90 mm height) keeps the board footprint compact, but the exposed pad requires a thermal via array under the centre for proper solder-joint reliability and thermal dissipation. Supply voltage spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V rails without an external regulator.

Frequency stability and temperature grade

Rated ±50 ppm frequency stability over -20°C to 70°C, which meets the timing margin for 1 GbE, PCIe Gen 1/2, and SATA interfaces without external VCXO compensation.
