DS8673 - Low Power VHF/UHF Prescalers

General Description

The DS8673 and DS8674 products are low power prescalers which divide by 64 and 256 respectively The devices are used in frequency synthesis applications such as TV CATV cellular phone and instrumentation to divide a very high frequency down to a frequency usable by low power MOS PLL’s The devices ha
