Description
The M64895BGP 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.
Features
• 4 integrated PNP band drivers (Io = 40 mA, Vsat = 0.2 V typ@Vcc 1 to 13.2 V)
• Built in tuning Amplifier for direct tuning.
• Low power dissipation (Icc = 20 mA, Vcc = 5 V)
• Built-in prescaler with input amplifier (fｍax = 1.3 GHz)
• PLL lock/unlock status display output (Built-in pull up resistor)
• I²C bus control (write mode only)
• X 3type of tuning steps (Division ratio 1/512, 1/640, 1/1024) with 4 MHz X’tal
• Programmable chip address
• Small package (16 Pin SSOP)
Application
• TV, VCR tuners
