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
