We have ADV7280 is connected with renesas S7G2. DVDDIO=3.3V,DVDD=1.8V,PVDD=1.8V,AVDD=1.8V RESET and PWRDWN pin is pulled-up to DVDDIO. SDA and SCL pin is pulled-up  to DVDDIO by 4.7kohm. We try to read register from 0x11(IDENT) with slave address 0x43. There is no ack from the device(ADV7280). There are other devices in the same I2C bus. Those… (Show more)

We use attached file named "OK-CVBS-ADV7842-BT656.txt" to check in EVAL-ADV7842-7511-P board, it's correct.Now, we put it into our board with ADV7842, it's very unreliable.the vide data like Figure 1 very casually can be observed.Figure 2 and 3 is sequential waveforms of ADV7842 output.The red line is pixel clock, the yellow is data clock.FAE of… (Show more)

Hi ADI Expert,   I have one video content whose resolution is 480p and format is RGB 24 bits.   I would like use ADV7343 to receive this signal and output CVBS, but this combination is not found in ED Configuration Scripts. Is this workable?   Can you please suggest the closest script and which register can be changed to fit this video input… (Show more)

I have the ADV7612-7511P eval board and running this script gets me some kind of output.  I took only the writes to address 72 and had my code write those same values to the 7511P on our own board, read them back to verify they took, and it does not generate any output.  We have not connected the I2C lines to the HDMI connector but it does not… (Show more)

When we are increase the resolution in an existing HDMI 1.4 system from 1080P@30Hz to UHD@30Hz sparkles appear in the video due to the connectors/cables in the system being inadequate which results in a degraded eye pattern. The right answer is to improve the cable/connectors and we're pursuing that. However, we also want to explore if the ADV7619… (Show more)

I managed to get the output to come on from our board, but it appears to reset every few seconds, with the output stopping, then starting back up again.  I thought that this might be because our LCD does not have a functioning DE signal. so I changed some of the registers in an attempt to get the chip to generate its own DE signal, but it did not… (Show more)

Hi,   The ADV7613 is an HDMI input device, with dual transmitter LVDS output, so I try to use ADV7613 to drive two identical LVDS display panels, now the ADV7613 can drive only one panel, I try to write 0x04 to Address  OLDI Map, 0x4E, but the lvds pll lost lock.    "In the dual LVDS transmitter mode, the output formatter blocks splits a single… (Show more)

This is regarding ADV212 JPEG2000 Programming Guide Rev 2.0 page 44. If RCTYPE is =1 (Target size within 5%). Is 5% a guarantee? If I allocate a memory buffer of RCVAL + 5% am I guaranteed not to overflow the buffer? Do you recommend oversizing the buffer to give more margin or is it a memory waste? Thanks!
