M64893FP/GP
SERIAL INPUT PLL FREQUENCY SYNTHESIZER FOR TV/VCR
DESCRIPTION
The M64893 is a semiconductor integrated circuit consisting of
PLL frequency synthesizer for TV/VCR using Bip process. It
contains the prescaler with operating up to 1.3GHz, 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 ampliï¬er (Fmax=1.3GHz)
⢠PLL lock/unlock status display out put
(Built-in pull up resistor )
⢠Xâtal 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
⢠Small package (SOP/SSOP)
