DS8673 DS8674 Low Power VHF UHF Prescalers
General Description
The DS8673 and DS8674 products are low power prescal-
ers 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 have differential buffered inputs and comple-
mentary ECL outputs The inputs provide high input sensitiv-
ity and good isolation The DS8673 is pin compatible with
Plessey’s SP4531 SP4632 and Motorola’s MC12073 prod-
ucts The DS8674 is pin compatible with Plessey’s SP4653
and Motorola’s MC12074 products
