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, long- life 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 Single operation (either ch ON): ICC OP1 = 2.7 mA TYP. @ VCC = 1.8 V Power save mode (both ch OFF): ICC PS = 10 µA MAX. @ VCC = 1.8 V • Decreased lockup time available: charge pump switch control (lockup time: 9 ms @ fstep = 12.5 kHz, 1 MHz swing, decreased lockup time mode). • 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.
