Auto Pixel-Per-Line Feature

For proper operation, the device requires the information of

number of pixels in DE high period. Program the pixel count

into registers 0x61 and 0x62. Alternatively, the device can

automatically count the number of pixels in DE high period.

Setting the AUTOPPL bit high enables this function. In this

mode, the device counts the number of pixels in every DE

high period and compares the result with the number of

pixels in the previous DE high period. If both numbers are

within ±4 pixels of each other, the deserializer accepts

this count as valid count and uses the number to pack-

etize the video data. An AUTOPPL error is issued only

when the current pixel count does not match the previous

pixel count. An invalid count (±5 or more pixels) stops the

packet transmission and issues an AUTOPPL error. This

allows the device to tolerate some noise while alerting the

user of an error.

Table 2 Video Output Map (RGB and YUV)

1. Refer to the GMSL serializer data sheet for details.

2. YUV defaults to muxed input mode (Cb, Y0, Cr, Y1). Set INPUTBW = 1 to use normal input mode (CBY0, CrY1).

3. Data type available when BWS = high or open, only.

*VESA/oLDI bits are mapped to MIPI according to OLDI bit (D4 or register 0x60). Set oLDI bit low when using VESA input or high

when using an oLDI input. oLDI defines bits [5:0] as MSB and bits [6:7] as LSB.

**12-bit YUV422 sent using CSI-2 user-defined data type (0x30). The output byte sequence is CB[11:4], Y0[11:4], [CB[3:0], Y0[3:0]],

CR[11:4], Y1[11:4], [CR[3:0], and Y1[3:0]].
