MC44829
PLL Tuning Circuit
with I2C Bus
The MC44829 is a tuning circuit for TV and VCR tuner applications. It
contains, on one chip, all the functions required for PLL control of a VCO.
This integrated circuit also contains a high frequency prescaler and thus
can handle frequencies up to 1.3 GHz. The circuit has a band decoder that
provides the band switching signal for the mixer/oscillator circuit. The
decoder is controlled by the buffer bits.
The MC44829 has programmable 512/1024 reference dividers and is
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)
• 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
• Operational Amplifier for Direct Tuning Voltage Output (30 V)
• Four Programmable Chip Addresses
• Integrated Band Decoder for the Mixer/Oscillator Circuit
• Band Buffers with Low “On” Voltage (0.4 V Maximum at 5.0 mA)
• Fully ESD Protected to MIL–STD–883C, Method 3015.7
(2000 V, 1.5 kΩ, 150 pF)
