µ
PB1510GV
3 GHz INPUT DIVIDE BY 4 PRESCALER IC
FOR DBS TUNERS
The
µ
PB1510GV is a 3.0 GHz input divide by 4 prescaler IC for DBS tuner applications. The
µ
PB1510GV is
suitable for use of frequency divider for PLL synthesizer block. The
µ
PB1510GV is a shrink package version of the
µ
PB585G so that this small package contributes to reduce the mounting space.
The
µ
PB1510GV is manufactured using NEC’s high f
T
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.

Functions and Explanation
Supply voltage pin. This pin must be equipped with
bypass capacitor (e.g. 1 000 pF) to minimize ground
impedance.
Signal input pin. This pin should be coupled to signal
source with capacitor (e.g. 1 000 pF) for DC cut.
Signal input bypass pin. This pin must be equipped with
bypass capacitor (e.g. 1 000 pF) to minimize ground
impedance.
Ground pin. Ground pattern on the board should be
formed as wide as possible to minimize ground
impedance.
Non connection pins. These pins should be opened.
Divided frequency output pin. This pin is designed as
emitter follower output. This pin can be connected to
input of prescaler within PLL synthesizer through DC cut
capacitor.
