VS6552

3.6 Control and Video Interface Formats

3.6.1 Overview

Data is transferred from VS6552 to STV0974 via a

high speed serial link (VisionLink). The serial data

link comprises of two pairs of wires. The serial

control data is transferred between the VS6552 to

3.6.2 VisionLink Physical Layer

Data signals (PDATAP and PDATAN) and clock

signals (PCLKP and PCLKN) are transferred from

VS6552 to STV0974 via 2 pairs of balanced 100

Ω

impedance transmission lines.

The transmission line pairs and custom transmit-

ters/receivers realize a very low voltage differential

(vLVDS) signalling scheme that can transfer infor-

mation in a potentially noisy environment. As im-

plemented in VS6552, VisionLink supports the

transmission of raw Bayer data at VGA resolution

up to 30 frame/s.

3.6.3 Serial I2C Control Bus

The internal registers in VS6552 can be config-

is the bus master and VS6552 is the single slave.

VS6552 sends and receives commands over this

bus at up to 400 kHz.

Table 6. Absolute Maximum Ratings

Note: Caution: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress

rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of

the specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
