４．Functional Description
4.1 General Description
4.2 Fanctional Discription
Feb./2005
TC90101FG also has a through mode and sync processing for 525p & 625p component signal.
TC90101FG is a Video decoder device for multi color system (525i. 625i).
1.TC90101FG has input interface for CVBS，S-Video, YＣbＣr. For RGB signal it needs some
10. VBI data slice function (525i ID-1/525p ID-1/ CCD/ WSS). It can be read via IIC.
11. Macrovision detection circuit.
12. Noise level detection circuit.
13. Superposition function for IIC read data on ITUR-656 ouitput.
1. Clock System
6. Frequncy detection circuit for 525i/525p/625i/625p for component signal.
7. AGC circuit circuit at after stage of ADC.
8. Picture processing circuit for CVBS, S-Video, 525i/625I component signal.
9. Selectable ITUR-601, ITUR-656 output interface.
2.0 Input interface
2.1 Selection input signal
external circuit as below.
2. Automatic clamp control circuit.
3. Multi 3line comb filter.
4. Multi color decoder and sync processing.
5. Color system detection circuit. (Selectable auto detection and manual setting.)
TC90101FG has a digital VCO circuit which uses 42MHz free run X’tal OSC.
Digital VCO circuit generates 27MHz fH clock for input stage, 4fsc clock for internal comb block
And 13.5MHz for output stage.
Result of color system dtection can be read via IIC.
Input signal can be set via INSEL at sub address 00hex.
INSEL : 00 : CVBS 01: S-Video 10: YCbCr 11: SCART( ** )
( * ) : it’s not available to input RGB signal dilectlly.
VBI data slice.
In this mode CVBS must be inputted to CVBIN for sync processing, noise dtection and
It’s needs RGB to YCbCr conversion circuit at the before stage of TC90101FG.
