C-1 Sage Operation
The s9050-100 is highly-integrated display processors. It has an ADC/PLL block and a
microprocessor integrated on a single chip. The cost-effective s9050-100 is suitable for the
XGA and the s9050 for the SXGA market segment with smaller memory requirements. Other
features include a brand new high-end scaler, Active Color Management, a flexible OSD,
Autoadjust, SureSync
TM
and independent monitoring of the analog interface. A new standalone
on-chip pattern generator has been incorporated to simplify the manufacture of monitors.
