7202 series
[32kHz output crystal oscillator module ICs]

Overview

The 7202 series is a 32.768 kHz output crystal oscillator IC.

It is compatible with AT-cut crystal resonators of 16.777216 MHz (divide-by-512), 25.165824 MHz (divide-by-768), and 33.554432 MHz (divide-by-1024).

Use of an AT-cut crystal makes it possible to create a 32.768 kHz output crystal oscillator with excellent temperature characteristics.

Three pad layout types are available to suit the package structure and mounting method, making it ideal for a variety of oscillator configurations.

*1. The recommended oscillation frequency is a yardstick value derived from the crystal used for NPC characteristicsauthentication. The oscillation frequency range is not guaranteed. 
    Specifically, the characteristics can vary greatlydue to crystal characteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.

*2. Versions in parentheses are under development and the negative resistance values are provisional. Please contact our sales for details on the latest versions.
