SERIAL INPUT PLL FREQUENCY SYNTHESIZER FOR TV/VCR

DESCRIPTION

The M64894 is a semiconductor integrated circuit consisting of

PLL frequency synthesizer for TV/VCR using I2C BUS control. It

contains the prescaler with operating up to 1.3GHz, 4 band drivers

and tuning Amplifier for direct tuning. Built-in 4 band drivers.

FEATURES

• 4 integrated PNP band drivers

(Io=40mA,Vsat=0.2V typ@Vcc1 to 13.2V)

• Built-in high-withstanding voltage tuning Amplifier

• Low power dissipation (Icc=20mA, Vcc=5V)

• Built-in prescaler with input amplifier (Fmax=1.3GHz)

• I2C bus control (Read and write mode)

• X’tal 4MHz is used to realize 3 type of tuning steps

(Division ratio 1/512, 1/640, 1/1024)

• Built-in 5-level A/D converter

• Programmable chip address

• 16-pin small SOP/SSOP package
