Product Details
__
PLL Tuning Circuit with DC-DC Converter, I2C Bus and ADC
**The MC44871 is a tuning circuit for TV, VCR and Multimedia tuner
applications. This device 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 MC44871 has an integrated dc/dc converter to generate the 30 V supply
voltage for the tuning amplifier on the chip. A tuner using the MC44871 does
not require an external 30 V supply.
The MC44871 is controlled by a I2C bus, and has a chip address function. The
MC44871 data format is the same as the MC44818.
The MC44871 is manufactured on a single silicon chip using Motorola’s high
density bipolar process, MOSAIC (Motorola Oxide Self Aligned Implanted
Circuits).
• The Pin Called VCC2 for the MC44818 is Now Called CP (Charge
Pump). This Pin is the Output of the DC/DC Converter; a 1.0 nF
Capacitor Replaces the Need for an External 30 V Supply
• High Speed I2C Bus (up to 800 kHz)
• I2C Bus Read Mode for Lock Detector and AFC Level
• HF Input is Balanced
• MC44871 has Three PNP High Current (30 mA) Band Buffers (B0, B1, B2) and One
NPN Low Current (5.0 mA) Band Buffer (B4)
• VCC Internally Supplies PNP Band Buffers
• The Tuning Voltage is Generated Through an External Pull–Up Resistor (750
kΩ)
• Less Phase Comparator Output Current
• Single 5.0 V Supply Operation
