Revision History
Document
Description
Date
C5115-DAT-01A
Initial release.
March 2001
C5115-DAT-01B
In Table 18 corrected description of OSC_SEL (on pin ROM_ADDR13). It should be set to 1 to
indicate usage of a single-ended clock oscillator.
Corrected image and orientation of logo in pin out diagram Figure 2.
Added section 4.11.3.
June 2001
C5115-DAT-01C
Replaced all occurrences of CVDD with CVDD_2.5, including pin numbers 26, 88, 134 and 203
to make them consistent with the names of other 2.5V voltage supply signals.
July 2001
C5115-DAT-01D
Pin number 205 name changed from GPIO16/HFS to GPIO16/HFSn and all occurrences of
HFS replaced with HFSn to reflect the fact that this signal is active low.
Added description of 2-wire serial protocol in section 4.17.2 and Table 24.
Removed "Read with Increment" operation description.
Corrected mechanical specification in Figure 32.
Changes to Table 21 DC Characteristics:
- Maximum voltage for 5V-tolerance inputs is 5.5V.
- Added maximum current requirements.
Added description of OCM Standalone configuration Figure 26.
Added Figure 22 Panel Power Sequencing.
July 2001
C5115-DAT-01E
Added description of gm5125 (SXGA device).
Pin names changed to reflect alternate hard-wired functions:
- pin 50 from GPIO11 to GPIO11/ROM_WEn,
- pin 51 from GPIO12 to GPIO12/NVRAM_SDA,
- pin 52 from GPIO13 to GPIO13/NVRAM_SCL,
- pin 6 from DDC_SCL to GPIO14/DDC_SCL,
- pin 7 from DDC_SDA to GPIO15/DDC_SDA,
- pin 46 from GPIO6 to GPIO6/TCON_SHC,
- pin 47 from GPIO7 to GPIO7/TCON_TDIV.
Removed description of 6-wire host interface, since this is not recommended operation. Pin 1
name changed from GPIO17/HDATA0 to GPIO17, and similarly for pins 206, 207 and 208.
Corrected maximum ADC sampling frequency in Table 15 and maximum ADC_CLK frequency
in Table 22 to 162.5MHz.
Added section 4.5 Test Pattern Generator.
Added description of TCON_SHC and TCON_TDIV in section 4.13.1.
Clarifications to section 4.1 describing clock generation, section 4.7.2 describing sRGB support,
and section 4.15.3 describing GPIOs.
Removed mention of row attributes in Figure 25.
gm5115/25 OSD controller does not have row attributes.
Corrected Table 21, Note 3. Pins VDD1_ADC_2.5, VDD2_ADC_2.5, VDD_RX0_2.5,
VDD_RX1_2.5 and VDD_RX2_2.5 are digital 2.5V supplies, not analog.
Changed signal names SCL and SDA to HCLK and HFSn, respectively in Figure 29, Figure 30,
and Figure 31.
August 2001
C5115-DAT-01F
Added note on Front Cover regarding HDCP enabled versions.
Added section 4.12 - Energy Spectrum Management (ESM).
Added clarification in section 4.13.1 indicating that single bus configurations are supported in
XGA column drivers only.
In section 4.16, clarified that ROM_ADDR[15:0] have internal 60K pull-down resistor.
Changes to Table 20 Absolute Maximum Ratings:
Renamed parameters
JA_XGA
,
JA_SXGA
,
JC_XGA
and
JC_SXGA
to
JA_5115
,
JA_5125
,
JC_5115
and
JC_5125
and revised their values.
Added note (4) regarding the maximum case temperature.
Changes to Table 21 DC Characteristics:
Renamed parameters P
5115
and P
5125
and revised their values.
Revised the values of P
LP
and I
LP
.
Renamed parameters I
5115
, I
5115_2.5_VDD
, etc.
Added note (6).
Removed the clock speed column from section 6 Ordering Information and added the ordering
information for gm5115-H and gm5125-H.
Replaced occurrences of TMDS with DVI.
Changed TCON_RCLK to TCON_ROWCLK in Figure 2 and in Table 7.
Changed RCLK to ROWCLK in 4.13.2 and in Figure 24.
