Description GM5862, GM5862H, GM5822H, GM5868H, GM5828H
1 Description
The GM58xx family of controllers are highly integrated mixed signal LCD controllers with
built-in panel RTC for LCD panels with slow grey-to-grey response time up to WUXGA
resolutions.
The integrated RTC only requires a single 1Mx16 SDR SDRAM to support a UXGA panel.
In most cases, the grey-to-grey response time can be reduced as much as half of the native
grey-to-grey response time. This depends on the characteristics of the target LCD panel.
The GM58xx monitor controller family has integrated proven ADC/PLLs and an UltraReliable DVI or HDMI 1.1 compatible digital receiver with optional FRC to ensure proven PC
graphics compatibility. The optional FRC function may need more external memory to
support up to SXGA 75 Hz.
The GM58xx family includes the following products:
● GM5862 supports up to 1920 x 1200 resolutions with DVI
● GM5862H supports up to 1920 x 1200 resolutions with DVI and HDCP
● GM5822H supports up to 1680 x 1050 resolutions with DVI and HDCP
● GM5868H supports up to 1920 x 1200 resolutions with HDMI and HDCP
● GM5828H supports up to 1680 x 1050 resolutions with HDMI and HDCP
