Supply voltage spans 2.5V to 3.3V, allowing direct connection to common 2.5V or 3.3V clock trees without an external regulator. The standby (power-down) function reduces supply current to 5 µA maximum, preserving battery charge in intermittently powered systems.
Housed in a 6-VDFN package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm, the footprint is compatible with standard 5×3.2 mm oscillator pads.
LVPECL (Low-Voltage Positive Emitter-Coupled Logic). This differential output requires proper termination — typically 50 Ω to VCC - 2V — and AC-coupling if driving a 50 Ω transmission line.
Yes, in most applications. The MEMS resonator offers equivalent ±25 ppm stability and a wider operating temperature range than many quartz XOs, with the added benefit of lower standby current (5 µA). The 6-VDFN package is footprint-compatible with standard 5×3.2 mm oscillator pads, so a board layout change is not required.
The standby (power-down) function disables the oscillator output and reduces supply current to 5 µA maximum. This allows the system to gate the clock during idle periods without removing supply voltage, preserving battery life in portable or energy-harvesting designs.
