THCV231_16 Datasheet, PDF (10/56 Pages) THine Electronics, Inc. – The THCV231 and THCV236 are designed to support video data transmission between the host and display.

Power Down (PDN1, PDN0, PDN)
PDN1, PDN0 and PDN turn off internal circuitry of Main-Link and Sub-Link separately.

Pre-emphasis and Drive Select Function (THCV231 only)
Pre-emphasis can equalize severe signal degradation caused by long-distance or high-speed transmission. PRE
register selects the strength of pre-emphasis. CMLDRV register controls CML Main-Link output swing level.

Permanent Clock Output (THCV236 only)
When there is no input from Main-Link, the THCV236 will output internal oscillator clock from CLKOUT pin.
This function is controlled by OUTSEL pin or OUTSEL_ENABLE register and OUTSEL_SETTING register.
See Table 5.
