  • Forum Post: A question about TVP5150

    Ray 16078
    I use TVP5150 as decoder, a composite PAL video as TVP5150 input siganl connected to AIP1A. FPGA config TVP5150 through I2C bus. I follow the datasheet of TVP5150 to send 09h to register 03h. The I2C communication wave in oscilloscope is right, but the TVP5150 Y output is always FFh. Who can give me...

    Hello all, I'm currently working with a TVP5150AM1, which is placed on an own developed PCB. This PCB is based on the reference design in the TVP5150AM1 datasheet. Only difference made is a 22pF capacitor instead of a 33pF which I calculated. The whole design is powered by a Power supply with both...

    HI, all I am using TVP5150A connecting with a PAL camera as input, and connect to DM642.The TVP5150 output is a standard ITU-R 8bit BT656 4:2:2 (720*576) with embedded synchronization(SAV and EAV).The DM642 is used to process the BT656 data.ALL function is OK .However the output video has a black...

    Viet Dinh
    Leon, The line ID can be larger or smaller than standard number of line if: The input signal is non-standard The input is pulled in/out when it is in the middle of the field. The line count does not reset until it detects a vsync. So, the backend can ignore the line ID that is greater than...

    Hi Zhengxu, No, it means if you want 720 active pixels output, you need to use firmware patch. Since the TVP5150 has 3 versions, can you give me the ROM version number in the register 82h? If it is 4 then it is TVP5150AM1 and we have a patch for it. Regards, Viet

    Hello, I'm using a TVP5150AM1 to decode a composite NTSC video signal that is being transmitted/received over an FM RF link. Occasionally, I see the Lost Lock Detect bit in Status Register #1 go high, along with a mixture of losing the color subcarrier, vertical sync, or horizontal sync lock (one...

    Jimmy Song
    Hello All, I have a question on the arrangement of register address in TVP5150, in document SLES043A. I have found that the addresses of registers are not consecutive: Register 1: 00h 2: 01h 3: 02h … 16: 0Fh 17: 1 1 h Where is 10h here? 18: 12h …...

    Steve Clynes
    Jim, If you refer to the datasheet you can see that these registers are reserved. For the TVP5150 table 3-8 lists the registers. For the TVP5150A table 2-9 lists the registers. For the TVP5150AM1 table 3-11 lists the registers. Note, only the TVP5150AM1 is now recommended for new designs...

    Hello Zheng, Sorry for the confusion. I have attached the diagram of the Configuration Shared Pins of I2C register 03h for explanation and detail how to select lock status. Basically it is a mux to select what lock status goes to pin 23 and 24. For example, if you want to output HVLK to pin 23, you...

    Hi Zheng, Please see response for each question below: 1. Lock mean the decoder is lock to video input signal. For example, if there is no video at the input, HLK and VLK will be 0. If the is a good input, HLK and VLK are 1 then you should see a good video output. If vertical is not lock, you will...

    The freescale does handle clock stretching so that it tolerates the TVP holding SCL low. Confirmed by o'scope. My reset timing and pulse duration is per TVP spec at power up and the I2C traffic is quiet per the same diagram. I2C pulls high with the rise of the power suplies. I currently don't...

    It is difficult to catch when and where becuase the fault is erratic.

    Thanks James. I see the patch download guidelines. What I have are old and new datasheets. The older (2006) says to write to 0x7C during a normal startup sequence. This tidbit is included in the RESET/POWERDOWN section. In the newer datasheet (2010), the RESET/POWERDOWN section no longer mentions this...
