1.8 to 5.5 V BIAS, 80 MHz to 550 MHz DUAL PLL FREQUENCY SYNTHESIZER
LSI FOR CORDLESS TELEPHONES AND PORTABLE CELLULAR RADIO

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.
