1. Outline

These specifications are hardware specifications of NV012-C (FPD-Link III d realizer board).

NV012-C (a following book board and the notation) is a conversion board for changing into a parallel

signal the image of the serial signal transmitted by the TI, Inc. FPD-Link III standard, and using it,

connecting with SV series (SVM-03/03 U/SVI-06 etc.) of our company.

[Fig. 1] Block diagram

The block diagram of this substrate is shown in [Fig. 1]. This substrate carries TI, Inc. デシリアライ

ザ IC DS90UB914 A-Q1, Serial - parallel conversion of the FPD-Link III picture signal to the 100

MHz of maximum pixel clock and the I2C communication through a FPD-Link III signal wire are

possible. The output connector of the parallel signal serves as an interface common to SV series, and

SV board and the use linked directly are possible. The connector of a FAKRA standard is used for the

input of a serial signal (single-ended transmission), and it is ideal for connection with the camera of

an in-vehicle use.

It is this substrate and SVM-03 to [Fig. 3]. The board connection image of a substrate is shown.

As shown in a figure, both substrates are connected through the pin socket (CN2) of 50 pins. Since a

screw hole position is common to both boards, it can fix both substrates by a spacer etc. The

arrangement plan of the connector of this substrate is as being shown in [Fig. 4]. The clause of "the

details of a connector" shows the pin number of a connector, and pin assignment later.

2. Details

2.1. Power supply system

1.8V regulator (LDO) is carried in this substrate, and this supplies the power supply to the core

voltage of デシリアライザ IC. Power supply (core voltage, IO voltage) of IC It supplies from SV

board of SVM-03 etc. through connector CN2. At this time, VDDH and VDDL of SV board correspond

to the core voltage and IO voltage of this substrate, respectively. Usually, both VDDH and VDDL are

set as 3.3V.

Moreover, in this substrate, the power supply for cameras can be superimposed on a FPD-Link III

cable. This power supply is supplied from CN5, CN6, or CN8. Since the power supply for cameras

and IC are divided in direct current through the capacitor, an injection order of the power supply of

IC and the power supply for cameras is not asked.

The block diagram of the electric power system of this substrate is shown in [Fig. 5]. When using

DC jack (CN6) which connects an AC/DC adaptor, in this substrate, in preparation for future

extension, the pattern of DC converter in which 12V input is possible is prepared, and voltage is

changed by jumper resistance mounted on the substrate. With NV012-C Since the jumper is set to

the DC jack side, a camera power supply can be supplied via DC jack by mounting CN6.

2.2. I2C function

デシリアライザ IC (DS90UB914A) of this substrate has I2 C bus, and has an I2C communication

function with Syria Liza and the target device which let the setting change in IC, and a FPD-Link III

cable pass. In this substrate, since the pull-up of the I2 C bus of DS90UB914A was carried out to IO

voltage by 4.7 komega and also it is directly linked with the connector for SV series, I2C

communication is possible for it by the standard function of SV series as it is. Simultaneously, since

I2 C bus is directly linked with the I2C input and output connectors (CN4) on a substrate, connection

with an external device and the operation from an external master are also attained.

At this substrate, the I2C address of DS90UB914A is 2 by a DIP switch (SW1). Kind change is

possible. For details, please refer to the clause of a DIP switch setup.

A camera power supply input connector (CN5, CN6, CN8) inputs DC power supply supplied to a

target device (camera) if needed. Please input a power supply from one of connectors according to

application or a system. This camera power supply is superimposed by the FPD-Link signal wire

when using CN1, and when using CN10, it is outputted to a specific pin. Moreover, a camera power

supply is not used inside a NV012-C board, but is supplied only to a target device. Required power

supply capacity is dependent on the characteristic of a target device.

Extended connectors (CN7, CN9) are the communication between substrates by a multi-channel

taking-in system, and a connector for future extension. I2C input and output connectors (CN4) are

directly linked with I2 C bus of DS90UB914A.
