157.2864 MHz MEMS clock for high-speed serial interfaces
157.2864 MHz is a common reference frequency for 10 Gigabit Ethernet (10GBASE-R), PCI Express Gen 3, and video clocking — the ±10 ppm holdover keeps the bit-error rate within the PHY's jitter tolerance.
MEMS resonator vs quartz — the reliability advantage
The base resonator is MEMS rather than a quartz crystal — MEMS oscillators are inherently more resistant to shock, vibration, and mechanical stress, making this a fit for industrial motor drives, outdoor telecom cabinets, and portable instrumentation where quartz can fail from board flex or drop events.
Supply voltage flexibility and power budget
Maximum supply current is 35 mA during active operation; the Standby (Power Down) function drops consumption to 95 µA max, which matters for battery-backed real-time clocks or power-gated subsystems.
Package and board layout
Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the small footprint and low profile suit dense PCB layouts in SFP+ cages, PCIe add-in cards, and compact compute modules.
It is suitable for new designs and volume production BOMs.
