Part Number: TVP5150AM1-EP
Other Parts Discussed in Thread: TVP5150A

What is the maximum resolution supported b TVP5150AM1-EP??

Will it support 720x576 resolution(standard PAL resolution)

[In datasheet, active pixels per line alone is menionted  as 720.]

    Pavithra,
    The TVP5150A supports PAL (B, D, G, H, I, M,N) formats.

    Just to let you know this device will be transitioning to NRND status soon. (Not Recommended for New Design). This status is only to indicate that we do not have in-depth application support for this device. It does not indicate that the device will no longer available or become obsolete.

    Hi Wade,
    As per datasheet it supports PAL (B, D, G, H, I, M,N) . As per standard; PAL resolution is 720 x 576.
    But I was asking, what is the IC's maximum HxW value ? "HxW value" as such is not mentioned in datasheet.

    Also what command is to be used to read the "Height x Width" value from TVP5150AM1-EP??

    Pavithra,
    Unfortunately, the only documentation I have is the datasheet and technical docs located here (in the commercial folder).
    www.ti.com/.../technicaldocuments

    To determine the resolution of standard video with autoswitch mode on, the detected video standard can be read from status register 5 address 0x8C.

    Hi Wade VonBergen,

    Reading 0x8C register is sufficient for me to write my application.
    With autoswitch on; I tried reading 0x8C register. 0x8C register gives "PAL" correctly. But "NTSC" is not correct.
    Because when video is disconnected, 0x8C register gave 0x81 which says "NTSC"; which is contradicting the scenario.

    [When NTSC is connected;0x8C register correctly gave 0x81. But it is not reliable since disconnected video also gave as NTSC.]

    Is there any other register which correctly gives "NTSC video detected" ?

    I found workaround for identifying NTSC video checking two conditions:
    C0h register [Interrupt Status Register A] :bit 7 == 0x1 &&
    0x8C register value == 0x81

    Hope this is the correct way to identify NTSC is actually connected.
    Thanks for your support..
