Overview

...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™ (M...
