TRIPLE 8-BIT ANALOG-TO-DIGITAL CONVERTER KB2516 (Preliminary) SUMMARY The KB2516 is a triple 8-bit analog-to-digital converter optimized for digitizing R/G/B graphics signal from PC and workstation. Its 140MSPS encode rate capability and analog bandwidth of 500MHz supports support display resolution of up to SXGA (1280 × 1024) class. The IC also includes a PLL (Phase Locked Loop) system that can be locked on horizontal line frequency, and generates the ADC clock. FEATURES Analog bandwidth of 500MHz 3 clamps for 256 programmable levels 3 programmable gain amplifiers Analog input range: 0.5Vpp to 1.0Vpp Triple 8-bit ADC Sampling rate up to 140MHz Fully integrated PLL to generate the ADC clock, which can be locked to a HSYNC Integrated PLL divider Programmable clock phase control (Φ step = 7.5°) Integrated SOG separator and HSYNC input polarity detector Single and double pixel width output data bus Support I2C and 3-wire serial interface Power down mode 1.25W power dissipation ORDERING INFORMATION Device KB2516 Package 144-LQFP-2020 Ordering Information APPLICATIONS RGB high speed digitizing LCD desktop monitor Plasma display pannel panel RELATED PRODUCTS KS2530 FRC & SCALER 1 KB2516 (Preliminary) TRIPLE 8-BIT ANALOG-TO-DIGITAL CONVERTER BLCOK DIAGRAM Blue Channel B_OUTA<7:0> Green Channel B_IN G_IN G_IN Red Channel ADC 8-bit Output Drver 8-bit B_OUTB<7:0> G_OUTA<7:0> G_OUTB<7:0> G_OUTA<7:0> R_OUTB<7:0> CLAMP CLAMP Gain Control Contro...
