DESCRIPTION
NEC's UPB1508GV is a Silicon RFIC digital prescaler manu-
factured with the NESAT™ IV silicon bipolar process. It fea-
tures frequency response to 3 GHz, a divide-by-two ratio, and
operates on a 5 volt supply while drawing only 12 mA. The
device is housed in a small 8 pin SSOP package that contrib-
utes to system miniaturization. The low power consumption
and wide frequency operation makes the device well suited for
use in a PLL synthesizer for UHF/VHF TV and DBS tuner
applications.
