Page 3: General Information
1.1 Functionality and Features of the 1000BASE-T1 SFP MODULE Figure 1-1: 1000BASE-T1 SFP MODULE The Technica Engineering 1000Base-T1 SFP Module fits into a standard Small Form- factor Pluggable slot. It uses the SGMII and generates 1000 Mbit/s full-duplex 1000BASE-T1. It is self-configurating after powerup to Automotive 1000BASE-T1. - Page 4 Weight: 0,1 kg International Protection: IP 2 0 Operating temperature: 0 to +70 °Celsius Integrated PHY 88Q2112_A0 from Marvell LINKS: The User can download the latest firmware and documentation for the 1000BASE-T1 SFP MODULE here: https://technica-engineering.de/produkt/1000base-t1-sfp-module/ 100BASE-T1 MediaConverter_BCM User Manual...

88Q2112_A0 transceiver by MDIO interface. This lasts 100ms. Do not apply any I2C activity on the bus during this time! 3.2 Self-Configuration The SFP Module configures itself to 1000BASE-T1 after power up. Master-/Slave Configuration is done according to the DIP switch on the bottom of the device. Figure 3-1: DIP-Switch To reconfigure the DIP switch the lock has to be opened (see pictures). -
Page 10: I2C Interface
3.3 I2C Interface 3.3.1 I2C configuration 100ms after power up of the module it can be configured by I2C. The module operates with f up to 53kHz without requiring clock stretching. The module may clock stretch with f greater than 53kHz and up to 400 kHz. The module processor listens as slave on the 7-bit address 0x50. -

Page 12: Random Address Read
Example: Read the current address of the SFP module (b1010000X). 3.3.3.2 Random address read The random address read requires two operations to perform the read. Example: Read a random address of the SFP module (b1010000X) First a write operation to specify the address desired to read: 100BASE-T1 MediaConverter_BCM User Manual... -
Page 13: Sequential Read
Then a read operation to read the previous address specified: 3.3.3.3 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 14: Byte Write
Then the read operations: 3.3.3.4 Byte Write The write operation requires 8-bits of data word address following the device address write word and acknowledgement. Example: Byte write operation into the SFP module (b1010000X) 3.3.3.5 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. -
Page 15: I2C Access To The 88Q2112_A0 Transceiver
3.3.4 I2C access to the 88Q2112_A0 transceiver The 88Q2112_A0 PHY listens as slave on the 7-bit address 0x40. Every internal register of the PHY (16 bits) is accessed by defining the Device Number (1 byte) and the Register address (2 bytes). The I2C Memory address is mapped as: Address Register name 0x00... - Page 16 o Bit 3 – Write Start Condition Flag (Read) This flag is set by the slave when a write operation is trigged. o Bit 4 – Write In Progress Flag (Read) This flag is set by the slave during the writing operation o Bit 5 –...
