UPD3140GS - DUAL PLL FREQUENCY SYNTHESIZER LSI

General Description

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

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

Key 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 pin.
  • Built-in power-save function: control 2 prescaler’s ON/OFF operation individually.
  • Low power consumption: Dual operation (both ch ON): ICC OP2 = 4.3 mA TYP. @ VCC = 1.8 V @ VC.

DATA SHEET BiCMOS INTEGRATED CIRCUIT µPD3140GS 1.8 to 5.5 V BIAS, 80 MHz to 550 MHz DUAL PLL FREQUENCY SYNTHESIZER LSI FOR CORDLESS TELEPHONES AND PORTABLE CELLULAR RADIO DESCRIPTION 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 at dual operation and 2.7 mA at single operation. The additional functions are high-speed lockup and lock phase sensitivity setting. The package is a 20-pin SSOP (300 mil) suitable for high-density surface mounting.
