M52727SP
PAL/NTSC SYSTEM SINGLE-CHIP COLOR TV SIGNAL PROCESSOR
DESCRIPTION
The M52727SP is an I²C bus interface built-in semiconductor IC
designed to process PAL/NTSC type image signals, color signals
and deflection signals. Provided with a switch for both S input and
AV, black extension function, etc., the M52727SP can meet a wide
range of devices from diffusion machines to large screen TV sets.
The addition of SECAM chroma-decoder M52325AP will enable
the M52727SP to completely and automatically identify the TV
systems used all over the world.
FEATURES
•Is capable of reading/writing data with the I²C bus control circuit.
•Built-in AV-SW (with volume control) that is also available for S
input
•Complete and automatic identification of color signals and vertical
synchronous frequencies of a TV system
•Improvement in the synchronization separation facility at the time
of synchronous compression by auto slicer
•Built-in black expansion circuit
•Built-in vertical phase adjustment function
•Built-in two SW systems (ON/OFF by bus control)
APPLICATION
PAL/NTSC Type Color TV, Projecter
RECOMMENDED OPERATING CONDITION
Recommended supply voltage ....... V24=5V, V9.47=8.2V, V20=9V
Operating supply voltage range ... V24=4.75 to 5.25V
V9.47=7.6 to 8.8V
V9.47=7.6 to 8.8V
V20=8.6 to 9.4V
Maximum Current ......................... 5.0mA (Pin 18 current)
5.0mA (Pin 13 current)
8.0mA (RGB current)
3.0mA (AUDIO OUT current)
1.0mA (Pin 12 current)
Note: Do not use the M52727SP when only the deflection type
power supply (pin 9 ) is made to rise. If so, normal horizontal
output pulse width cannot be obtained. Keep away 1 m or
more from the IC when using a portable telephone.
