SERDES24-35OVT/NOPB

SERDES24-35OVT Evaluation Kit for OV7710 Image Sensor Application with a FPD-Link II (DS90C241/DS90C124) Serial Interface SERDES24-35OVT Rev 0.2 Description: The SERDES24-35OVT is an evaluation kit designed to demonstrate performance and capabilities of the DS90C124 and DS90C241 FPD-Link II Serializer/Deserializer Chipset for use with the OmniVision “CLOTHO” development system that features the OV7710 640 x 480 Color Image Sensor. This serves as an add-on to the OmniVision development system, providing a serialized digital interface between camera and controller. The DS90C241 Serializer board accepts LVCMOS input signals from the Image Sensor and provides single serialized FPD-Link II LVDS data pair as an output. The DS90C124 Deserializer board accepts the FPD-Link II LVDS serialized data stream and converts the data back into parallel LVCMOS signals and clock that connects to the OmniVision USB Host Board. Contents: • • One DS90C241 Serializer board One DS90C124 Deserializer board What the user needs to provide: • • • • • OmniVision OV7710 Demo Board OmniVision USB Board CAT5 cable External 5V power supply PC with USB interface and Omnivision software (or alternate control interface) SER DES 5V OVT USB Board OVT Imager Figure 1. Imager - Serializer and Deserializer - Controller Connections Setup instructions: 1. Connect the DS90C241 Serializer board to the Omnivision OV7710 Demo Board. Refer to Figure 1. SERDES24-35OVT Rev 0.2 2. Connect the DS90C124 Deserializer board to the OmniVision USB Board. Refer to Figure 1. 3. Connect the DS90C241 Serializer board to the DS90C124 Deserializer board via the CAT5 cable. 4. Connect 5V power to the Deserializer board 5. Push “ON” button (S2) on Deserializer board. Green light should now be visible on RJ45 connectors at Serializer (J3) board and Deserializer (J6) board. 6. Connect PC/Controller to the Deserializer board via USB cable. Green light should be visible on USB controller board (D2). 7. Launch Omnivision software (or alternate control application) Troubleshooting: Problem… No image No green light on RJ45 connectors No green light on USB board All lights on, but no image No image SERDES24-35OVT Solution… Check that all RJ45 and USB green lights are on Check that 5V power supply is provided, and CAT cable connection is good Cycle “ON” button on deserializer board Check that USB is connected to PC Check that orientation of board connections is correct Check that lens cap is removed from camera Rev 0.2 IMPORTANT NOTICE Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements, and other changes to its products and services at any time and to discontinue any product or service without notice.
