X98027
FN8221.0
275MHz Triple Video Digitizer with
Digital PLL
The X98027 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 275MSPS conversion
rate supports resolutions up to QXGA at 60Hz refresh rate,
while the front end's high input bandwidth ensures sharp
images at the highest resolutions.
To minimize noise, the X98027'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 275MSPS Analog-to-Digital Converters (ADCs).
Automatic Black Level Compensation (ABLC™) eliminates
part-to-part offset variation, ensuring perfect black level
performance in every application.
The X98027's digital PLL generates a pixel clock from the
www.DataSheet4U.com
analog source's HSYNC or SOG (Sync-On-Green) signals.
Pixel clock output frequencies range from 10MHz to 275MHz
with sampling clock jitter of 250ps peak to peak.
