M64893AFP/AGP
SERIAL INPUT PLL FREQUENCY SYNTHESIZER FOR TV/VCR
Description
The M64893AFP/AGP is a semiconductor integrated
circuit consisting of PLL frequency synthesizer for
TV/VCR using Bip process. It contains the prescaler with
operating up to1.3GHz,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=1.3GHz)
PLL lock/unlock status display out put
(Built-in pull up resistor )
X`tal 4MHz is used to realize 1 type of tuning
steps (Division ratio 1/640)
Serial data input (3 wire bus )
Built-in Power on reset system
