Description

The CGS3311, CGS3312, CGS3313, CGS3314, CGS3315, CGS3316, CGS3317, CGS3318 and CGS3319 devices are designed for Clock Generation and Support (CGS) applications up to 110 MHz. The CGS331x series of devices are crystal controlled CMOS oscillators requiring a minimum of external components. The 331x devices provide selectable output divide ratio (and selectable crystal drive level). CGS3311 is designed to operate over a wide frequency range using fundamental model or overtone crystals.
