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 (Φstep = 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
