Overview

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.
Thus, this product contributes to produce physically-small, low power-consumption, longlife battery systems.
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 @ VCC = 1.
8 V @ VCC = 1.
8 V Single operation (either ch ON): ICC OP1 = 2.
7 mA Power save mode (both ch OFF): ICC PS = 10 µA lockup time mode).
TYP.
MAX.
• Decreased lockup time available: charge pump switch control (lockup time: 9 ms @ fstep = 12.
5 kHz, 1 MHz swing, decreased • Lock phase sensitivity programmable: Phase difference allowance for lock up can be controlled as 4 stages (150 ns to 5 µs).
• Pins and counter data are compatible to µPD2844BGS (except option data).
• High-density surface mounting: 20-pin plastic SSOP.
