DS8627 Datasheet 130/225 Mhz Low Power Prescalers

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: DS8627 DS8628 130 225 MHz Low Power Prescalers June 1986 DS8627 DS8628 130 225 MHz Low Power.

General Description

The DS8627 and DS8628 are low power fixed ratio prescalers which divide by 24 and 20 respectively The inputs can be driven either single or double-ended and they are buffered providing 40 100 mVrms input sensitivity The output provided is open-collector and is capable of interfacing with TTL and CMOS The device can be used in phase-locked loop applications such as FM radio or other munications bands to prescale the input frequency down to a more usable level A digital frequency display system can also be derived separately or in conjunction with a phase-locked loop and it can extend the useful range of many inexpensive frequency counters to 225 MHz
