MC44824/25

PLL Tuning Circuits

with I2C Bus

The MC44824/25 are tuning circuits for TV and VCR tuner applications.

They contain on one chip all the functions required for PLL control of a VCO.

The integrated circuits also contain a high frequency prescaler and thus can

handle frequencies up to 1.3 GHz.

The MC44824/25 are manufactured on a single silicon chip using

Motorola’s high density bipolar process, MOSAIC™ (Motorola Oxide Self

Aligned Implanted Circuits).

• Complete Single Chip System for MPU Control (I2C Bus). Data and

Clock Inputs are 3–Wire Bus Compatible

• Divide–by–8 Prescaler Accepts Frequencies up to 1.3 GHz

• 15 Bit Programmable Divider

• Reference Divider: Programmable for Division Ratios 512 and 1024

• 3–State Phase/Frequency Comparator

• 4 Programmable Chip Addresses

• 3 Output Buffers (MC44824) respectively 5 Output Buffers (MC44825)

for 10 mA/15 V

• Operational Amplifier for use with External NPN Transistor

• SO–14 Package for MC44824 and SO–16 for MC44825

• High Sensitivity Preamplifier

• Fully ESD Protected
