UPD3140GS Datasheet (NEC) - DUAL PLL FREQUENCY SYNTHESIZER LSI

UPD3140GS, DUAL PLL FREQUENCY SYNTHESIZER LSI

µPD3140GS is a dual PLL frequency synthesizer LSI designed for cordless telephones and portable cellular radio.

This LSI is manufactured using 13 GHz fT BiCMOS process and integrated 2 pairs of prescaler + PLL operate from 80 MHz to 550 MHz.

This LSI realizes low power consumption: on 1.8 V, 4.3 mA

UPD3140GS Features

* Supply voltage: VCC1 = VCC2 = 1.8 to 5.5 V

* Input operating frequency: fin = 80 MHz to 550 MHz (PLL 1ch, 2ch in common)

* Reference oscillating frequency fref = 30 MHz MAX.. Built-in high-speed reference oscillator signal can be taken out from the buffer amplifier output p
