4.12 Parallel Camera Interface

There are two camera module connectors present on infotainment expansion board to support parallel camera interface:

  • 32 pin Omni Vision camera module connector
  • 36 Pin Leopard imaging camera module connector

Parallel camera data & SYNC signals from both connectors are connected to a 2x 2:1 Camera selection MUX IC Part#: SN74AVCB164245VR. GPIO signal CAM_SEL_OV# is used to select between OV-camera and LI-Camera modules. By default, OV camera signal path is enabled. For GPO mapping, see Section A.2.

The output of camera selection mux is connected to VIN/VOUT selection mux. To route the parallel camera signals to VPFE port of SoC, see Table 10 and Section A.2.

SPI, Reset, PCLK and Power down signals are terminated with Camera connector through 3x level translation circuit IC Part# SN74AVC4T245DGVR (U3, U4 and U5). Camera I2C signals are level translated using IC part# PCA9306DCT.

NOTE

Camera modules will not be the part of delivery kit.
