SERIAL INPUT PLL FREQUENCY SYNTHESIZER FOR TV/VCR
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 1.3GHz, 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)
• I²C bus control (Read and write mode)
• X’tal 4MHz 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
