(Preliminary) PL610-32 1.8V to 3.3V XO IC – Divide by 512 FEATURES DESCRIPTION Wide operating voltage: 1.8V to 3.3V (+/-10%) Built-in 512 divider. 16.777216MHz fundamental frequency, generates 32.768KHz output clock. Low power consumption: 0.13mA @ 1.8V Output enable/disable function provide stand by mode to turn off oscillator and output buffer. Very low standby power consumption: 0.2uA 2mA output drive Operating temperature range from -40C to 85C PL610-32 is a member of PhaseLink’s PicoXo and is designed to fit in a small 2mmx1.6mm form-factor (or larger) ceramic module. It can operate from a single power supply ranging from 1.62V to 3.63V and consumes ultra low-power. PL610-32 is a crystal oscillator module IC with a built-in 512 divider, which can accept 16.777216MHz fundamental frequency crystal source and produce 32.768KHz output with excellent temperature characteristics.
