M64895FP/GP
I2C BUS FREQUENCY SYNTHESIZER FOR TV/VCR
DESCRIPTION
The M64895 is a semiconductor integrated circuit consisting of PLL
frequency synthesizer for TV/VCR using I2C BUS control. It
contains the prescaler with operating up to1.3GHz, 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)
• PLL lock/unlock status display out put
• (Built-in pull up resistor )
• I2C bus control (write mode only)
• X’tal 4MHz is used to realize 3 type of tuning steps
(Division ratio 1/512, 1/640, 1/1024)
• Programmable chip address
• Small package (16Pin SOP/SSOP)
