CHIPIDEA's 210MHz Analog Interface for Flat Panel Displays Validated in Silicon at 0.18um TSMC
Square Silicon Achievement
Silicon results show that CI7375tg and all its sub-blocks are silicon validated meeting all its specification parameters.
With a SNR better than –42.9dB at 210MS/s and an INL of ±1.1 LSB, CI7375tg exceeds current requirements for flat panel video rendering.

Square Brief Description
CI7375tg is a complete 3-channel AFE interface for Flat Panel Display. It captures the analog RGB or YUV graphic signals generated on a PC or other device, and converts them into three 8-bit digital words with video resolution up to 210 MHz.It includes all necessary video system functions such as flexible clamping modes, synchronism extraction, separation and pixel clock generation. The good performance achieved with these functions makes CI7375tg a powerful and competitive Analog Interface for an integrated video system.
