FPI-954-HF / NV015-C

Hardware Specification 1.0

1. Overview

This is a hardware specification of FPI-954-HF / NV015-C (FPD-Link III deserializer board).

This board is mounted the TI company deserializer DS90UB954, and converts the video of the serial

signal transmitted by FPD-Link III standard to MIPI signal. This is a conversion board connected

with our MIPI monitoring board SVM-06.

This board has FAKRA (coaxial) and HSD (differential) connectors. The coaxial input supports

PoC (Power over Coax). On the differential input side, the camera power can be output to a specific

pin of the HSD connector. The output connector is a 60-pin connector that can be connected not only

to our SVM-06 but also to the older model SVM-MIPI.

Block diagram

The block diagram of this board is shown above. This board is mounted the TI company

deserializer IC DS90UB954, so it can receive the max. 4Gbps FPD-Link III video signal including

1080p/60fps and I2C communication through the FPD-Link III signal line. MIPI CSI-2 output of

DS90UB954 is connected to the connector for MIPI monitoring board SVM-06 (CN3), so this board

can be connected directly with SVM-06. The FAKRA connector and HSD connector are mounted for

serial signal input and it makes ideal for automotive camera applications. The camera power is

supplied from either the dedicated connector CN5, CN6, or CN8, and the coaxial side is powered by

the PoC circuit on the board and the differential side is powered by a specific pin on the HSD

connector to the camera. The board power is supplied from SVM-06 or other monitoring boards

through the connector CN3.

The figure below shows the board connection image of this board and SVM-06 board. As shown

in the figure, both boards are connected with a 60-pin connector (CN3). Since the screw hole position

is common, it is possible to fix both boards with a spacer. This board has the FPD-Link III input

connectors (CN1, CN2), and supposes to be connected the DS90UB953 as serializer. When you

choose CN2 input, you need to set the DS90UB954 register separately from the DIP SW setting. The

connector model number and PIN assignment are shown later in Details section.

Hardware Specification 1.0

This board is implemented Power over Coax (PoC) circuit for superimposing power to the coaxial

cable. The PoC circuit for CN2 is shown below. The filter circuit is a constant paired with DS90UB953.

- If you need to change the component constants of the PoC circuit, please contact us before ordering.

3.2. Power

The power (core power, IO Power) of the deserializer IC DS90UB954 is supplied through the

CN3 from the connecting board (SVM-06, etc.). The core power supply is 1.8V and the power is

supplied to the deserializer by a 1.8V regulator (LDO) on this board. The IO power supports 1.8V,

3.3V, and supplied to the VDDIO voltage of CN3.

This board can also be superimposed on the FPD-Link III cable for camera power (VCAM). This

VCAM power is supplied from the connector CN5, CN6, or CN8, and is powered to the coaxial cable

through the PoC circuit. The differential side is output to a specific pin of the HSD connector. Since

the power supply for the camera and the NV015-C internal power supply are DC separated through

capacitors, the order in which the power is turned on does not matter.

3.3. I2C Bus

The deserializer IC DS90UB954 of this board has an I2C bus, which has the function to change

the configuration in the IC and the function of I2C communication between the serializer and the

target device through the FPD-Link III cable. The I2C bus of DS90UB954 is pulled up to the IO

voltage (VDDIO) with 4.7kΩ, and it is directly connected with the SVM-06 connector. I2C

communication is possible with a PC as the standard function of SVM-06. At the same time, the I2C

bus is directly connected to the I2C input/Output connector (CN4) on this board, so allowing

connections to external devices and operations from an external master.

I2C address of DS90UB954 can be changed to four types by DIP switch (SW1). Refer to DIP

Switch Settings section for more information.

3.4. REFCLK

The 25MHz crystal oscillator is connected to this board for the DS90UB954 Reference Clock

(REFCLK).

- Implementation states apply to NV015-C.

- The expansion connector (CN9) is for inter-boards communication and future expansion in an input

system using multi boards.

- The camera power input connector (CN5, CN6, CN8) inputs the DC power supply to the target device

(camera) as needed. Depending on the application or system, input the power from one of the

connectors. The camera power is superimposed on the coaxial cable or is output to a specific pin of HSD

connector, and is not used inside the NV015-C board. The required power capacity depends on the

target device. The input voltage of the camera power should be 16V or less.

- The I2C I/O connector (CN4) is directly connected to the I2C bus of the deserializer IC (DS90UB954).
