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 1.3 GHz. 4 band drivers and tuning amplifier for direct tuning.

Built-in 4 band drivers.

Features

• 4 integrated PNP band drivers (IO = 40 mA, Vsat = 0.2 V Typ@VCC1 to 13.2 V)

• Built-in high-withstanding voltage tuning Amplifier

• Low power dissipation (ICC = 20 mA, VCC = 5 V)

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

• I2C bus control (Read and write mode)

• X’tal 4 MHz 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

Function

• 2-modulus prescaler (1/32 and 1/33)

• Built-in 4 MHz crystal oscillator and reference divider

• Programmable divider (10-bit M counter, 5-bit S counter)

• Tri-state phase comparator

• Lock detector

• Band switch driver

• Op.Amp for direct tuning

• I2C bus receiver
