Dual-frequency HCSL clock source in a compact MEMS package
Housed in a 14-VFQFN Exposed Pad package measuring 3.20 mm x 2.50 mm with a 0.90 mm height, it fits tight board layouts where a quartz oscillator and its decoupling would consume more area.
Supply voltage tolerance and temperature grade
Supply voltage range is 2.25 V to 3.6 V — it runs from a 2.5 V or 3.3 V rail without an external regulator, and the wide tolerance covers the drop across a ferrite bead or a long PCB trace. Frequency stability is ±25 ppm across the temperature range — enough for most PCIe Gen 1/2/3 reference clocks and 1000BASE-T Ethernet without needing a TCXO.
Active production and MEMS reliability advantage
This matters for equipment shipped to sites with mechanical handling or fan vibration.
