3.0 GHz INPUT DIVIDE BY 4 PRESCALER IC
FOR DBS TUNERS
DESCRIPTION
The UPB1510GV is a 3.0 GHz input divide by 4 prescaler IC for DBS tuner applications. This IC is suitable for use
of frequency divider for PLL synthesizer block. This IC is a shrink package version of the
µ
PB585G so that this small
package contributes to reduce the mounting space.
This IC is manufactured using our 20 GHz fT NESAT IV silicon bipolar process. This process uses silicon nitride
passivation film and gold electrodes. These materials can protect chip surface from external pollution and prevent
corrosion/migration. Thus, this IC has excellent performance, uniformity and reliability.
FEATURES
• High operating frequency : fin = 0.5 to 3.0 GHz
• High-density surface mounting : 8-pin plastic SSOP (4.45 mm (175) )
• Low current consumption : ICC = 14 mA TYP. @ VCC = 5 V
• Fixed division : ÷ 4
APPLICATIONS
• Prescaler between local oscillator and PLL frequency synthesizer included modulus prescaler
• DBS tuners with kit use of VHF/UHF band PLL frequency synthesizer

This pin must be equipped with bypass capacitor (example: 1 000
pF) to minimize ground impedance.
2 IN − 1.7 to 4.95 Signal input pin.
This pin should be coupled to signal source with capacitor (example:
1 000 pF) for DC cut.

4, 5 GND 0 − Ground pin.
Ground pattern on the board should be formed as wide as possible
to minimize ground impedance.
6, 8 NC − − Non connection pins.

NOTES ON CORRECT USE
(1) Observe precautions for handling because of electro-static sensitive devices.
(2) Form a ground pattern as widely as possible to minimize ground impedance (to prevent undesired oscillation).
(3) Keep the wiring length of the ground pins as short as possible.
(4) Connect a bypass capacitor (example: 1 000 pF) to the VCC pin.
