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
