MOTOROLA ANALOG IC DEVICE DATA
The MC44826 is a tuning circuit for TV and VCR tuner applications. It
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 circuit has a band decoder that
provides the band switching signal for the mixer/oscillator circuit. The decoder
is controlled by the buffer bits or independently by extra bits T6 and T7.
The MC44826 has a programmable 512/1024 reference divider and is
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 (I2C Bus)
Divide–by–8 Prescaler Accepts Frequencies up to 1.3 GHz
15 Bit Programmable Divider
Reference Divider: Programmable for Division Ratios 512 and 1024
3–State Phase/Frequency Comparator
Operational Amplifier for Direct Tuning Voltage Output (30 V)
Four Programmable Chip Addresses
Integrated Band Decoder for the Mixer/Oscillator Circuit
Band Buffers with Low “On” Voltage (0.4 V Maximum at 15 mA)
Fully ESD Protected to MIL–STD–883C, Method 3015.7
(2000 V, 1.5 k
, 150 pF)
