gm2110/20 Preliminary Data Sheet
Revision History
Document Description
Date
C2120-DAT-01A
Initial release
Nov 2001
C2120-DAT-01B
Changed title from gm2120 to gm2110/20 Data Sheet
In Figure 10, the recommended ADC input termination resistance changed
from 100 ohms to 20 ohms and 57.6 ohms for the RED+ and RED- signals
respectively, as these values yield better performance
Clarified that input formats with resolutions higher than that supported by the
LCD panel are supported as recovery modes only in section 4.3.2
Corrected the shrink description in section 4.7.2
Added section 4.13.3 ISP of FLASH ROM Devices
Added section 4.13.4 UART Interface.
Added section 4.13.5 DDC2Bi Interface
Added gm2110 DC Characteristics to Table 18 & Table 19 in section 5.1
Added gm2110 ordering information in section 6
April 2002
D2120-DAT-01C
Pins 143 ~ 146: changed xxx_SDDS or xxxx_SDDS to xxx_DDDS or xxxx_DDDS
respectively
Pins 138 ~ 141: changed xxx_DDDS or xxxx_DDDS to xxx_SDDS or xxxx_SDDS
respectively
Pins 147 ~ 148: changed xxx_DPLL to xxx_RPLL
