DS8615 Datasheet 130/225 Mhz Low Power Dual Modulus Prescalers

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: DS8615 DS8616 130 225 MHz Low Power Dual Modulus Prescalers July 1992 DS8615 DS8616 130 225 MHz Low Power Dual Modulus.

General Description

The DS8615 series products are low power dual modulus prescalers which divide by 32 33 and 40 41 respectively The modulus control (MC) input selects division by N when at a high TTL level and division by N a 1 when at a low TTL level The clock inputs are buffered providing 40 100 mVrms input sensitivity The two outputs provide the user the option to wire either a totem-pole or open-collector output structure Additionally the user can wire a resistor between the two output pins to minimize edge transition emissions The outputs are designed to drive positive edge triggered PLLs These products can be operated from either an unregulated 5 5V to 13 5V source or regulated 5V g 10% source Unregulated operation is obtained by connecting VS to the source with VREG open Regulated operation is obtained by connecting both VS and VREG to the supply source 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
