DESCRIPTION
NEC's UPB1506GV and UPB1507GV are Silicon MMIC digital
prescalers manufactured with the NESAT™ IV silicon bipolar
process. They feature high frequency response to 3 GHz,
selectable divide-by-64, 128, or 256 modes, and operate on a
5 volt supply while drawing only 19 mA. The devices are
housed in a small 8 pin SSOP package that contributes to
system miniaturization. These devices are designed for use in
a PLL synthesizer for DBS and CATV settop and WLAN
applications.

Signal input pin. This pin should be coupled to the source with a capacitor
(eg 1000 pF).
Signal input bypass pin. This pin must be equipped with a bypass
capacitor (eg 1000 pF) to ground.
Ground pin. Ground pattern on the board should be formed as wide as
possible to minimize ground impedance.
Divided ratio input pin. The ratio can be controlled by the following input
data to these pins.
