BIPOLAR DIGITAL INTEGRATED CIRCUIT
PB1511TB
µµµµ
800 MHz INPUT DIVIDE BY 2, 4 PRESCALER IC
FOR PORTABLE SYSTEMS
The
PB1511TB is a silicon monolithic integrated circuit designed as a divide by 2, 4 prescaler IC for portable
µ
radio systems. This IC is manufactured using NEC’s 30 GHz f
process.
Consequently, this IC is lower circuit current and smaller package than conventional µPB1509GV.
FEATURES
Operating frequency : f
•
Low current consumption : 3.5 mA @ VCC = 3.0 V
•
High-density surface mounting : 6-pin super minimold
•
Supply voltage : VCC = 2.4 to 3.3 V
•
Selectable division :÷ 2, ÷ 4
•
in
= 50 to 700 MHz @ ÷ 2,
50 to 800 MHz @ ÷ 4
max
UHS0 (Ultra High Speed Process) silicon bipolar
APPLICATIONS
Portable radio systems
•
Cellular/cordless telephone 2nd local prescaler
