DESCRIPTION
NEC's UPB1508GV is a Silicon RFIC digital prescaler manufac-
tured with the NESAT™ IV silicon bipolar process. It features
frequency response to 3 GHz, a divide-by-two ratio, and oper-
ates on a 5 volt supply while drawing only 12 mA. The device
is housed in a small 8 pin SSOP package that contributes 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.

Voltage Voltage
1 VCC 4.5 to 5.5 Power supply pin. This pin must be equipped with
bypass capacitor (eg 1000 pF) to ground.
2 IN 1.7 to 4.95 Signal input pin. This pin should be coupled with a capacitor (eg 1000 pF).
3 IN 1.7 to 4.95 Signal input bypass pin. This pin must be equipped with a bypass capacitor
(eg 1000 pF) to ground.
4, 5 GND 0 Ground pin. Ground pattern on the board should be formed as wide as possible to
minimize ground impedance.
6 NC No connection. This pin should be left open.
7 OUT 1.0 to 4.7 Divided frequency output pin.
This pin should be coupled to load device with a capacitor (eg 1000 pF).
8 NC No connection. This pin should be left open.
