TOSHIBA is continually working to improve the quality and the reliability of its product.
Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent
electrical sensitivity and vulnerability to physical stress. It is the responsibility of the buyer, when
utilizing TOSHIBA products, to observe standards of safety, and to avoid situations in which a
malfunction or failure of a TOSHIBA product could cause loss of human life, bodily injury or
damage to property. In developing your designs, please ensure that TOSHIBA products are used
within specified operating ranges as set forth in the most recent products specifications. Also,
please keep in mind the precautions and conditions set forth in the TOSHIBA Semiconductor
Reliability Handbook.

Functional Description
4.1 General Description
TC90101FG is a Video decoder device for multi color system (525i. 625i).
TC90101FG also has a through mode and sync processing for 525p & 625p component signal.
1.TC90101FG has input interface for CVBS S-Video, Y b r. For RGB signal it needs some
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.)
Result of color system dtection can be read via IIC.
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.
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
TC90101FG has a digital VCO circuit which uses 42MHz free run X’tal OSC.

2.1 Selection input signal
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.
It’s needs RGB to YCbCr conversion circuit at the before stage of TC90101FG.
In this mode CVBS must be inputted to CVBIN for sync processing, noise dtection and
VBI data slice.
