Quad LVPECL timing source with MEMS reliability
The MEMS resonator eliminates the aging and vibration sensitivity of quartz crystals — a real advantage in systems that see shock or wide temperature swings, such as outdoor small cells or industrial Ethernet switches.
Stability and temperature grade for outdoor deployment
Rated at ±25 ppm frequency stability over the -40°C to 85°C industrial temperature range, this oscillator holds the clock edge tight enough for 10/100/1000BASE-T jitter budgets without an external TCXO — a common gotcha when designers assume a basic XO will pass the Ethernet mask at temperature extremes.
Supply flexibility and enable/disable control
The 2.25V to 3.6V supply range lets the same BOM position serve 2.5V and 3.3V rails — useful when a board has both voltage domains and you want one clock part number across both.
Package and layout consideration
Housed in a 20-VFQFN with exposed pad measuring 5.00 mm x 3.20 mm and 0.90 mm height, the package footprint is compact but the thermal pad underneath must be soldered to a ground plane with adequate thermal vias — skipping this step can cause frequency drift under load.
