Page 3: Feature List
1 Feature List The Technica Engineering 100Base-T1 SFP module fits into a standard Small Form-factor Pluggable slot. ® It uses the SGMII and generates 100 Mbit/s full-duplex BroadR-Reach . ® After PowerUp it self-configures to Automotive BroadR-Reach Registers of the integrated transceiver are accessible via I2C interface for diagnosis and re-configuration. -
Page 4: Warranty And Safety Information
2 Warranty and Safety Information Before operating the device, read this manual thoroughly and retain it for your reference. Use the device only as described in this manual. Use only in dry conditions. Do not apply power to a damaged device. Do not open the device. -
Page 5: Pinning
3 Pinning ® The BroadR-Reach line is connected by a Molex connector. Hardware Version 2.4 and above use: - Molex 0533250260 Header 2.0mm - Molex 510900200 Housing -Molex 50212-8000 Crimp Contact Pin Function Function ® ® BroadR-Reach Plus BroadR-Reach Minus SFP Socket connector: Pin Function Function... -
Page 6: Startup And Configuration
4 Startup and Configuration 4.1 Startup After 3.3 Volt power is applied, the SFP module starts up and self-configures the BCM54811S transceiver by I2C interface. This lasts 100ms. In the first 100ms the processor on the module acts as I2C master. Do not apply any master activity on the bus during this time! 4.2 Self-Configuration ®... -
Page 7: I2C Interface
5 I2C Interface 5.1 I2C configuration I2C can be used 100ms after the power up of the module. The module operates with f up to 100kHz without requiring clock stretching. The module may clock stretch with f greater than 100kHz and up to 400 kHz. The module processor listens as slave on the 7-bit address 0x50. -
Page 8: Device Addressing And Operation
5.3 I2C Device addressing and operation 5.3.1 I2C Current address read The current read operation only requires the device address read word to be sent. When the acknowledge is received from the SFP module, the current address data word is serially clocked out. -
Page 9: Sequential Read
Then a read operation to read the previous address specified: <-I2C_device -> <- DATA WORD-> 5.3.3 Sequential read The sequential reads are started by either a current word address read or a random address read. To specify a sequential read, the host responds with an acknowledge instead of a stop after each data word. -
Page 10: Sequential Write
Example: Byte write operation into the SFP module (b1010000X) <-I2C_device -> <-MEMORY ADDRESS-> <-DATA WORD-> 5.3.5 Sequential write The sequential write is started in the same way as a single byte write, but the host master does not send a stop condition after the first word is clocked in. <-I2C_device ->... -
Page 11: Frequently Asked Questions - Faq
6 Frequently Asked Questions – FAQ ® Q: What is the maximum BroadR-Reach cable length? ® The BroadR-Reach Port is optimized for automotive UseCase. The maximum ® line length for each BroadR-Reach segment is limited to 10 meters. Q: The BR Link LED is lit but I have no valid BR Link. What is going wrong? A: There is a bug in the used BroadR-Reach PHY. -
