ｆ） AGC function
ID-1 data slicing is performed at line 20 and 283 in the vertical blanking period.
The sliced data is stored to IIC read register and it is performed at every field.
ID-1 data slicing is performed at line 41 in the vertical blanking period for NTSC 525p signal.
The sliced data is stored to IIC read register and it is performed at every field.
CCD data slicing is performed at line 21 and 284 in the vertical blanking period.
CRI detection, start bit detection and sliced data can be read via IIC bus.
The sliced data is stored to IIC read register and it is performed at every vertical blanking periode.
Noise level detection is performed in the vertical blanking period. The result of noise level detection is
stored to IIC read register and it is performed at every field.
The related write registers are as follows.
EN NOISEV S (sub address 1B hex) : Setup of start line for noise detection.
EN NOISEV W (sub address 1A hex) : Setup of the numbers of lines for noise detection .
EN NOISEH S (sub address 1A hex) : Setup of start position for noise detection at selected line.
EN NOISEH W(sub address 1A hex) : Setup of the period for noise detection at selected line.
WSS data slicing is performed at line 23 and 336 in the vertical blanking period.
The sliced data is stored to IIC read register and it is performed at every field.
The result of Macrovision detection can be read via IIC bus.
RUN-IN detection, start ｃｏｄｅ detection and sliced data can be read via IIC bus.
TC90101FG can detect a pseudo sync, AGC pulse and color stripe.
TC90101FG has an AGC function for CVBS and Y signal (S-video).
The related write registers are as follows.
PKLIM (sub address 2B hex) : Setup for limit level for PEAK AGC function.
PAGCON (sub address 2B hex) : Setup for PEAK AGC function.
SAGCON (sub address 2B hex) : Setup for SYNC AGC function.
(Through mode : Both registers (PAGCON & SAGCON) must be set [0]. )
