phyCAM-L VZ-018 phyCAM-M Bridge HW Guide

Overview

The VZ-018 Bridge converts the coaxial phyCAM-L interface to a phyCAM-M interface.

phyCAM-L is based on the FPD-Link III from Texas Instruments. The link is full-duplex capable and transmits, among other things, image data from the camera module via the forward channel. The backchannel works in the direction of the camera module and transmits control signals such as GPIOs and I²C. 

phyCAM-L uses a coaxial connection as a transmission medium which provides not only the data but also Power over Coax (PoC).

The bridge can be connected to any fully developed phyCAM-M interface. The power supply for the bridge and the camera module is provided by the phyCAM-M interface of the baseboard. Additionally, an external voltage source can be connected to use higher voltages and currents for PoC.

phyCAM Concept

The phyCAM series of camera modules allow for the easy and efficient configuration of microcontroller designs with image processing technology.

Camera modules with phyCAM interface can be directly connected to the digital camera interface of selected PHYTEC microcontroller modules. This allows for easy integration of camera technology into compact, project-specific designed products. Many BSPs (Board Support Packages) of PHYTEC microcontroller modules already contain the corresponding software drivers for the phyCAM modules.

Due to the open interface definition, phyCAM modules can also be used together with other microcontrollers or hardware designs that have a corresponding camera interface.

The interfaces of the phyCAM products are identical within the respective product series. This makes it possible to connect different camera modules with the same application circuit and allows scalability during the design phase and in future design variants.

Evaluation kits are available for the development phase.

Function Overview VZ-018

FPD-Link III

The FPD-Link III works with the DS90UB953 and DS90UB954 devices from Texas Instruments. The DS90UB954 deserializer is installed on the bridge.

Camera modules use the DS90UB953 serializer.

The link can transmit a gross data rate of 3.68 Gbps to 4.16 Gbps on the forward channel.

The backward channel operates at 50 Mbps.

The data rates depend on the reference clock used.

Further information can be found in the datasheets of the two devices.

Overcurrent Shutdown

The VZ-018 Bridge has an overcurrent shutdown to protect the used phyCAM-M interface.

If the current flow exceeds 1.5 amps, the phyCAM-M interface is disconnected from the power supply. The overcurrent (OC) led will then light up.

The voltage supply is released again by pressing the S1 button.

Power-Over-Coax

The power supply for the camera module is provided via Power-Over-Coax.

Three options are available for generating the PoC voltage:

When using an external voltage supply (X12), make sure that the voltage used is as free as possible from ripple or noise (<75 mV).

Check the voltage losses on the coaxial line. The minimum supply voltage of the camera module must not be undercut.

The quality of the power supply influences the subsequent maximum possible line length and current flow.

FPD-LINK III Reference Clock

The DS90UB954 deserializer requires a reference clock. This may be between 23 and 26 MHz.

In order to support as many PHYTEC development kits as possible, the VZ-017 Bridge works with a reference clock of 24 MHz.

The following data rates are derived from this:

• Gross data rate FPD-Link III: 3840 Mbps
• Gross data rate MIPI CSI-2: 3072 Mbps
• I2C clock (configurable)
• Master Clock (MCLK) of the camera module (configurable)

For verification purposes, the CMLOUT pins of the DS90UB954 are accessible at TP4 and TP5. CMLOUTN is connected to TP4 and CMLOUTP to TP5. Both signals are terminated against each other with 100 Ohm.

phyCAM-L Interface

The VZ-018 Bridge provides two phyCAM-L ports. To use the maximum bandwidth of the respective phyCAM-L interface, simultaneous operation of PORT0 and PORT1 is not intended.

For parallel operation please refer to the DS90UB954 datasheet. PHYTEC currently does not provide software support for parallel operation.

Further information about the phyCAM-L interface can be found in  L-867Be.A0 phyCAM Digital Camera Modules Concept and Design-In Guide. 

phyCAM-M Interface

Further information can be found in  L-867Be.A0 phyCAM Digital Camera Modules Concept and Design-In Guide.

Status LEDs

Four status LEDs are available.

X13 GPIO Extension Connector

Two additional GPIOs and a ground connection are provided on the 2.54 mm header.
