The CGS332x series of devices are crystal con-Crystal frequency operation range: trolled CMOS oscillators requiring a minimum of external fundamental: 10 MHz to 100 MHz typical components. The 332x devices provide selectable output 3rd or 5th overtone: 10 MHz to 95 MHz divide ratio. The circuit is designed to operate over a wide 1000V ESD protection on OCS_IN and OSC_OUT pins. frequency range using fundamental mode or overtone crys- 2000V ESD protection on all other pins tals. Output current drive of 48 mA for I /I OL OH FACT CMOS output levels Output has high speed short circuit protection Intended for Pierce oscillator applications Hysteresis inputs to improve noise margin CGS3321 has duty cycle adjust CGS3322 has 1, 2, 4 divide ratio Ordering Code: Order Number Package Number Package Description CGS3321M M08A 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow CGS3322M M08A 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow Devices also available in Tape and Reel.
