It operates from a 2.25V to 3.6V supply rail, drawing 35 mA max, and includes a standby (power down) function that drops supply current to 95 µA max when disabled. Frequency stability is ±25 ppm, which covers most Ethernet, USB, and general-purpose clocking needs without the cost of a TCXO.
The 6-VDFN exposed pad package (7.00 mm x 5.00 mm, 0.90 mm seated height) needs a thermal pad on the PCB for heat sinking — the exposed pad also helps with EMI containment.
Yes, the part includes a Standby (Power Down) function. When the enable pin is pulled low, the oscillator stops and the supply current drops to 95 µA max. This is useful for battery-powered or duty-cycled systems where the clock can be gated to save power.
