Part Number: SN75DP130

Hi,

Do you have eye-mask spec for the input side of SN75DP130 main link terminals that running at 1.62Gbps?
This is to use sink this device.

Best regards,
Shimizu

    Please refer to DP spec.

    For HBR2, the EYE diagram EYE width/height requirements are listed in Table 3-21 for downstream device compliance.

    For HBR/RBR, the polygon in Figure 3-39 represents the minimum entry EYE into the downstream device at TP3 for RBR and at TP3_EQ for HBR.
    Table 3-25 and Table 3-26 contain the values to be used for the vertices of the downstream device mask for high bit rate and reduced bit rate, respectively.

    You also need to refer to Table 3-22 for the jitter budget.

    Thanks
    David

    Hi David,

    I add a question about this post.

    My customer has VESA DisplayPort Standard Version 1, Revision 1a (January 11, 2008).
    In case of this document, Are "Figure 3-20 : Mask at TP3" and "Table 3-17 Sink EYE Vertices at TP3 for Reduced Bit rate" the mask that you mention?

    Best regards,
    Shimizu

    This is correct, please also refer to Table 3-16 for HBR data rate.

    Thanks
