Description

The M64898GP is a semiconductor integrated circuit consisting of PLL frequency synthesizer for TV/VCR /PC.

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 (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 M64892/M64893

• Automatic switching of tuning step according to the number of data bits (62.5 kHz at 18 bits, 32.25 kHz at 19 bits)

• Built-in Power on reset system

• Small package (SSOP)

Application

PC, TV, VCR tuners

Recommended Operating Condition
