TFP410: Compatible with AM335x?

Part Number: TFP410
Other Parts Discussed in Thread: AM3352

Hi Team,

My customer wants to implement HDMI display from Sitara processor AM3352, I am wondering if TFP410 is technically feasible to sit between AM3352 and HDMI display as the DVI transmitter? .

Below is the snapshot from AM3352 datasheet-

Regards,

Charles

    TFP410 can support RGB888 with the maximum resolution/frame rate depends on the amount of total pixels and required pixel clock frequency. In general, the max supported resolution for this device is 1920x1080@60Hz.

    Let us take a look at the DC electrical characteristic of TFP410 and AM3352 and make sure they are able to match with each other.

    Thanks

    Hi David,

    Thanks for your reply.

    Please let me know if there is any updated comment about pairing TFP410 with AM3352.

    Regards,

    Hello, Charles,

    For your reference

    The TFP410 VDD Supply voltage (DVDD, PVDD, TVDD) is 3.0 V (min) 3.3 V (typ)  3.6 V (max) whereas the AM3352, VDDS_DDR  is 1.8 V/1.5 V/1.35 V.

    You need to operate the TFP410 in the low-swing mode where adjustable 1.1-V to 1.8-V signaling levels are used when interfacing with the AM3352. Please see section 7.3.2 Universal Graphics Controller Interface Voltage Signal Levels of the datasheet. 

    TFP410 VIH High-level input voltage (CMOS input) minimum is Vref + 0.2 where Vref is between 0.5 V ≤ Vref ≤ 0.95 V. The AM3352 High level output voltage, driver enabled, pullup or pulldown disabled minimum when VDDS_DDR = 1.35 V is 0.95 V. Therefore, the TFP410 VIH and the AM3352 VOH specifications are compatible here since the AM3352 VOH is greater than or equal to the TFP410 VIH. The AM3352 VOL and TFP410 VIL are also compatible. 

    Note, the TFP410 can only be used as a HDMI transmitter for HDMI video-only. 

    Thanks,

    Zach
