Description

The CGS3321 and CGS3322 devices are designed for Clock Generation and Support (CGS) applications up to 110 MHz. The CGS332x series of devices are crystal controlled CMOS oscillators requiring a minimum of external components. The 332x devices provide selectable output divide ratio. CGS3321 is designed to operate over a wide frequency range using fundamental mode or overtone crystals.
