The MC44827/27B 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 MC44827 has programmable 512/1024 reference divider while the

MC44827B has a fixed reference divider of 1024.

LOW–POWER

PLL TUNING CIRCUIT

The MC44827/27B offer the same features as MC44817/17B but has

improved sensitivity performance and reduced power dissipation. The low

frequency preamplifier has been removed and the operational amplifier

pull–up resistor has been increased to 60 kΩ.

1.3 GHz PRESCALER

SEMICONDUCTOR

TECHNICAL DATA

The MC44827/27B are controlled via a 3–wire bus. The MC44827/27B

have the same functions as the MC44828 which is I C bus controlled. The

MC44827/27B and the MC44828 can be exchanged to allow conversion

between 3–wire bus and I C bus control.

The MC44827/27B 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 (3–Wire Bus). Data and

Clock Inputs are I C Bus Compatible

• Divide–by–8 Prescaler Accepts Frequencies up to 1.3 GHz

• 15 Bit Programmable Divider Accepts Input Frequencies up to 165 MHz

• 3–State Phase/Frequency Comparator
