DESCRIPTION
The X98027's digital PLL generates a pixel clock from the analog
source's HSYNC or SOG (Sync-On-Green) signals. Pixel clock
output frequencies range from 10MHz to 275MHz with long-term
clock jitter less than 250ps peak to peak.

Key Features
– Resolutions Up To QXGA 60Hz
– 250ps Long Term Jitter
– 64 Phase Choices
– Zero Offset Error/Offset Drift
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 strigent
requirements of the graphics display industry. The 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 resolution.
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). All necessary reference
voltages are internally generated.
