BIPOLAR DIGITAL INTEGRATED CIRCUIT
UPB1509GV
NEC's 1.0 GHz
DIVIDE BY 2/4/8 PRESCALER
FEATURES
• HIGH FREQUENCY OPERATION TO 1 GHz
• SELECTABLE DIVIDE RATIO: ÷2, ÷4, ÷8
• WIDE SUPPLY VOLTAGE RANGE: 2.2 TO 5 V
• LOW SUPPLY CURRENT: 5.3 mA
• SMALL PACKAGE: 8 pin SSOP
• AVAILABLE IN TAPE AND REEL
DESCRIPTION
NEC's UPB1509GV is a Silicon RFIC digital prescaler manu-
factured with the NESAT™ IV silicon bipolar process. It fea-
tures frequency response to 1 GHz, selectable divide-by-two,
four, or eight modes, and operates from a 3 to 5 volt supply
while drawing only 5.3 milliamps. The device is housed in a
small 8 pin SSOP package that contributes to system miniatur-
ization. The low power consumption and wide supply range
makes the device well suited for cellular and cordless tele-
phones as well as DBS receiver applications.
