PCF2120TK/1,118

Programmable Timers And Oscillators Overview

The PCF2120TK/1,118 is a CMOS quartz oscillator designed for low power consumption. It generates a 32.768 kHz output signal gated by an enable input. The device operates within a supply voltage range of 1.5 V to 5.5 V and features two integrated oscillator capacitors. It includes an internal power-on reset and utilizes a push-pull output configuration. The component is housed in an HVSON10 package (SOT650-1) with dimensions of 3 mm x 3 mm x 0.85 mm.
