PLL TUNING CIRCUIT
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.

WITH HIGH SPEED I C BUS
AND 30 V TUNING SUPPLY
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.
SEMICONDUCTOR
TECHNICAL DATA
2
The MC44871 is controlled by a I C 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 V
CC2
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

A representative block diagram and typical system
application are shown in Figures 1 and 8. A discussion of the
features and function of each of the internal blocks is given.
The Programmable Divider
The programmable divider is a presettable down counter.
When it has counted to zero it takes its required division ratio
out of the latches B. Latches B are loaded from latches A by
means of signal TDI which is synchronous to the
programmable divider output signal.

Since latches A receive the data asynchronously with the
programmable divider; this double latch scheme is needed to
assure correct data transfer to the counter.

The Operational Amplifier
Figure 6. Equivalent Circuit of the Integrated
PNP Band Buffers
The operational amplifier is designed for very low noise,
low input bias current and high power supply rejection. The
positive input is biased internally. The operational amplifier
output (Pin 1) needs an external 750 kΩ pull–up resistor (560
kΩ minimum). This minimum value is defined by the charge
pump output current capability.

“On”/“Off”
The oscillator uses a 3.2 or a 4.0 MHz crystal tied to ground
in series with a capacitor. The crystal operates in the series
resonance mode.
The voltage at Pin 15 has low amplitude and low harmonic
distortion.
