SERIAL INPUT PLL FREQUENCY SYNTHESIZER FOR TV/VCR

DESCRIPTION

The M64892 is a semiconductor integrated circuit consisting of

PLL frequency synthesizer for TV/VCR using Bip process. It

contains the prescaler with operating up to 1.0GHz, 4 band drivers

and Op. Amp for direct tuning.

FEATURES

• 4 integrated PNP band drivers

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

• Built-in Op. Amp for direct tuning voltage output (33V)

• Low power dissipation (Icc=20mA, Vcc1=5V)

• Built-in prescaler with input amplifier (Fmax=1.0GHz)

• PLL lock/unlock status display out put

(Built-in pull up resistor )

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

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

• Serial data input. (3 wire bus)

• Software and pin compatible with M64092/M64892

• Automatic switching of tuning step according to the number of

data bits (62.5kHz at 18bits, 31.25kHz at 19bits)

• Built-in Power on reset system

• 16-pin small SOP/SSOP package
