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
