Description
The M64897GP is a semiconductor integrated circuit consisting of PLL frequency synthesizer for TV/VCR/PC using
I2C BUS control. It contains the prescaler with operating up to 1.3 GHz, 4 band drivers and DC/DC converter for
Tuning voltage.
Features
• Built-in DC/DC converter for Tuning voltage
• 4 integrated PNP band drivers (IO = 30 mA, Vsat = 0.2 V Typ.@VCC1 to 10 V)
• Built-in prescaler with input amplifier (f max = 1.3 GHz)
• PLL lock/unlock status display out put (Built-in pull up resistor)
• X’tal 4 MHz is used to realize 3 type of tuning steps (Divider ratio 1/512, 1/640, 1/1024)
• Software compatible with M64894
• Built-in Power on reset system
• Small Package (SSOP)
Application
PC, TV, VCR tuners
Recommended Operating Condition
