March 8, 2006 140MHz Triple Video Digitizer with Digital PLL
The X98014 3-channel, 8-bit Analog Front End (AFE)
contains all the components necessary to digitize analog
RGB or YUV graphics signals from personal computers,
workstations and video set-top boxes. The fully differential
analog design provides high PSRR and dynamic
performance to meet the stringent requirements of the
graphics display industry. The AFE’s 140MSPS conversion
rate supports resolutions up to SXGA at 75Hz refresh rate,
while the front end's high input bandwidth ensures sharp
images at the highest resolutions. Features To minimize noise, the X98014's analog section features 2
sets of pseudo-differential RGB inputs with programmable
input bandwidth, as well as internal DC restore clamping
(including mid-scale clamping for YUV signals). This is
followed by the programmable gain/offset stage and the
three 140MSPS Analog-to-Digital Converters (ADCs).
Automatic Black Level Compensation (ABLCв„ўпЂ© eliminates
part-to-part offset variation, ensuring perfect black level
