1. Outline

This specification is a hardware specification of NV022-A (FPD-Link III Serializer substrate).

NV022-A (hereinafter referred to as this board) is equipped with the TI company Deserializer

DS90UB953 , converting a video signal entered in the MIPI format to a FPD-Link III signal. This

substrate has a coaxial-output connector of the Fakra standard and a connector to connect to our

SVO-MIPI series board. It can be applied to the emulation of the FPD-Link III camera combined

with the SVO-MIPI board. Differential outputs with STP cables are custom supported.

Block diagram

A block diagram of this board is shown in the figure above. The input Connector (CN2) of the MIPI

signal is supposed to be connected with our video output board and can be used directly with the

SVO-MIPI substrate. As an option, we have set up a pattern that can be equipped with a PIC

microcomputer for an I2C slave emulation purpose. The FPD-Link III output is a single-ended

FAKRA-standard connector. The board power supply is supplied from the SVO-MIPI video output

board through the connector CN3.（It does not support the PoC.）

The figure below shows the board connection image of the board and the SVO-MIPI board. Since

the screw hole position is common on both substrates, it is possible to fix both substrates with a

spacer or the like.

3.4. DIP Switch Settings

An 8-bit DIP switch (SW1) is implemented on this board, allowing the initial configuration of the

serializer DS90UB953 , the I2C address, and the decoupling of the I2C bus.

3.4.1. SW1 (DS90UB953 Setting / I2C Connection Settings)

SW# Name Description

1 I2C_SCL When the dip switch is on, the I2C bus which is output to cn3, and

the DS90UB953 I2C bus are connected. If off, both I2C buses will

be disconnected.

2 I2C_SDA

3 (Reserved) (Reserved)

4 IDX0 Specifies the I2C address of the ds90ub953. Specifies the IO

voltage for the I2C bus.

IDX0 | IDX1 | IDX 2 |

OFF | OFF | OFF | I2C Address = 0x18, 1.8V

ON | OFF | OFF | I2C Address = 0x19, 1.8V

OFF | ON | OFF | I2C Address = 0x18, 3.3V

OFF | OFF | ON | I2C Address = 0x19, 3.3V

Please note that there is an error in the silk printing on the board.

5 IDX1

6 IDX2

7 PDB Set the power down mode.

ON: Power down

OFF: Normal operation

8 (Reserved) (Reserved)

- As for the default, only IDX1 (5) is ON.

3.5. LED Indicator

LED# Name Description

D1 POWER If the 3.3V is supplied, it will be lit.

3.6. I2C Bus

Although this board has one I2C bus, it is possible to detach the I2C bus between the serializer and

the SVO-MIPI board (connector CN3 side) to prevent I2C address contention. By setting the

switch SW1 #1 and #2 to ON, the SVO board and the serializer's I2C bus are connected. The I2C

bus in the serializer DS90UB953 is also connected to the I2C I/O connector CN4.

The DS90UB953 I2C address can be changed to two types by DIP switch (SW1). See the DIP

Switch Settings section for more information.

This board provides a pattern that allows you to implement PIC microcontrollers and ISP

connectors in case you need to set the initial board startup or implement an I2C slave. This PIC

microcontroller is not usually implemented.

3.7. Power

The power supply of the serializer IC DS90UB953 is supplied from the connecting board

(SVO-MIPI, etc.) through the CN3. The core power supply and IO power supply is 1.8 V, which is

powered to serializer by a 1.8 v regulator (LDO) on the board. Because the IO power supply is fixed

to 1.8 V, the IO voltage of the device to which the SVO-MIPI is connected must be set to 1.8 v.

3.8. GPIO

In this substrate, the GPIO0-3 pin of the serializer IC (DS90UB953) is connected via a jumper

resistor to the GPIO8-11 (PIN number 22, 26, 32, 34) of the connector CN3, from the SVO-MIPI

substrate It is a configuration that can be a controll. You can also disconnect the GPIO by making the

R59-R63 un-implemented.
