64 Data channels

●

1 Control channel

●

1 Clock channel

The 64 data channels are used to transfer 8-bit, 10-bit or 12-bit data words from sensor to receiver.

The output clock channel transports a DDR clock (max 300 MHz), synchronous to the data on the

other LVDS channels. This clock can be used at the receiving end to sample the data. The data on the

control channel contains status information on the validity of the data on the data channels, among

other useful sensor status information. Details on the LVDS timing and format can be found in section

7.3 of this document.

7.1.4

Sequencer

The on-chip sequencer will generate all required control signals to operate the sensor from only a few

external control signals. This sequencer can be activated and programmed through the SPI interface.

7.1.5

SPI Interface

The SPI interface is used to load the sequencer registers with data. The data in these registers is used

by the sequencer while driving and reading out the image sensor. Features like windowing,

subsampling, gain and offset are programmed using this interface. The data in the on-chip registers

can also be read back for test and debug of the surrounding system.

7.1.6

Temperature Sensor

A 16-bit digital temperature sensor is included in the image sensor and can be controlled by the SPI-

interface. The on-chip temperature can be obtained by reading out the register with address 127.

7.2

Operating the Sensor

This section explains how to connect and power the sensor, as well as basic recipes of how to

configure the sensor in a certain operation mode.

Information

All register values are in decimal notation unless otherwise specified.

7.2.1

Power Supplies

To power the sensor, five externally generated supplies are required (VDD18, VDD33, VDD_PIX and

VDD_RES).
