FOR 3–WIRE BUS WITH
1.3 GHz PRESCALER

MOTOROLA ANALOG IC DEVICE DATA
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.
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.
The MC44827/27B are controlled via a 3–wire bus. The MC44827/27B
have the same functions as the MC44828 which is I2C bus controlled. The
MC44827/27B and the MC44828 can be exchanged to allow conversion
between 3–wire bus and I2C 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 I2C 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
• Operational Amplifier for Direct Tuning Voltage Output (30 V)
• Four Integrated PNP Band Buffers can drive up to 40 mA
(V
CC1
to 14.4 V)
• Output Options for the Reference Frequency and the
Programmable Divider
• Bus Protocol for 18 or 19 Bit Transmission
• Extra 34–Bit Protocol for Test and Further Features
• High Sensitivity Preamplifier
• Lower Power Consumption, 200 mW Typical
• Improved Prescaler with Higher Margins for Sensitivity and
Temperature Range
• Lock Detector with Push–Pull Output
• Space–Saving TSSOP Package
• ESD Protected to MIL–STD–883C, Method 3015.7 (1.5 kΩ,100 pF)

NOTE: 1. This part may be used with an external pull–up resistor of 20 kΩ to remain compatible with MC44817/17B
designed tuners. Pin 6 is left open. The internal pull–up can also be used with an external resistor in parallel.
