Digital Diagnosis 4.1 I2C Bus Interface The I2C interface allow reading of diagnostic information from the module. It is comprised of I2C DATA and I2C CLK pins. All address and data bytes are transmitted through the I2C DATA pin. The I2C DATA and I2C CLK pins are open-collector and they must be pulled high (4.75k recommended) externally to the module. Data on the I2C DATA pin may only change during I2C CLK 'low' time periods. Data changes during I2C CLK 'high' periods will indicate either a START or STOP condition. Operations and conditions are described as follows: START Condition The START condition is originated by the host. A high-to-low transition of I2C DATA while I2C CLK 'high' defines a START condition that must precede any other command, see Figure 4-1. STOP Condition The STOP condition is originated by the host. A low-to-high transition of I2C DATA while I2C CLK 'high' defines a STOP condition, see Figure 4-1. START STOP I2C DATA I2C CLK Figure 4-1: I2C START and STOP Condition Acknowledge or ACK Condition The acknowledge condition occurs when the I2C DATA pin is pulled 'low' during the ninth clock pulse following an address or data byte. The module originates this condition after it has received a block or data address. The host originates this condition during a sequential address read operation. Addressing Operation The module must receive a block address following a START condition to enable a read operation. The block address is clocked into the module MSB to LSB. There are three read operations: current address read, random read, and sequential address read. Note that by the convention specified in the SFP MSA, 7-bit block addresses are left shifted by one bit when expressing them in hex. Block addresses for the different GO2929 1310nm MSA Compatible Optical Transceiver Data Sheet 56644 - 1 June 2011 11 of 26 memory regions are specified in Section 4.2. Block addresses A0h, A2h, and B2h would therefore be transmitted defined as binary 1010000, 1011001 and 1011001 respectively. Current Address Read Operation The module has an internal register that maintains the data address used during the last read operation, incremented by one. If the most recent data address was FFh, then the register resets to 00h. Once the block address is clocked in by the host with the R/W bit set 'high', the module follows with an ACK condition, and the data byte located at the current data address is serially clocked out of the module MSB to LSB. The operation is terminated when the host does not provide an ACK condition and initiates a STOP condition. See Figure 4-2. START I2C DATA Block Address Read Data Byte STOP 7 6 5 4 3 2 1 R A 7 6 5 4 3 2 1 0 ACK Host driving data line NO ACK Module driving data line Figure 4-2: I2C Current Address Read Operation Random Address Read Operation A random read operation requires a dummy write sequence to load in the data address. Once the block and data addresses are clocked in by the host followed by an ACK condition provided by the module, the host must generate another START condition. The host now initiates a current address read operation by sending the block address with the R/W bit set 'high'. The module provides an ACK condition and serially clocks out the data byte. The operation is terminated when the host does not provide an ACK condition and initiates a STOP condition. See Figure 4-3. START I2C DATA Block Address Write Data Address START 7 6 5 4 3 2 1 W A 7 6 5 4 3 2 1 0 A Read Data Byte STOP 7 6 5 4 3 2 1 R A 7 6 5 4 3 2 1 0 ACK ACK Host driving data line Block Address ACK NO ACK Module driving data line Figure 4-3: I2C Random Access Read Operation Sequential Address Read Operation The sequential address read operation is initiated by either a current address read or random address read operation. After the host receives the first data byte, it responds with an ACK condition. As long as the module receives the ACK condition after a data byte is read, the host can clock out additional data bytes from the module. After the data address reaches FFh, it resets to 00h. The operation is terminated when the host does not provide an ACK condition and initiates a STOP condition. See Figure 4-4.

The bullet items below outline the different block addresses of the module: * Block address A0h contains serial ID information of the module. * Block address A2h contains alarm and warning flags, thresholds and real-time digital diagnostic features set. The 16-bit digital diagnostic monitoring information is internally calibrated over Gennum's specified operating temperature and voltage. Alarm and warning threshold values are calibrated in the same manner and can be interpreted as defined below. Internally measured module temperature is represented as a 16-bit signed two's complement value in increments of 1/256C, yielding a total range of -128C to +128C. To calculate the temperature, treat the two's complement value as a 16-bit unsigned integer and divide it by 256. If the result is greater or equal to 128, subtract 256 from the result. See Table 4-1 for temperature conversion examples. Table 4-1: Temperature Conversion Examples MSB (BIN) LSB (BIN) Temperature (C) 01000000 00000000 64C 01000000 00001111 64.059C 01011111 00000000 95C 11110110 00000000 -10C 11011000 00000000 -40C Internally measured module supply voltage is represented as a 16-bit unsigned integer with the voltage defined as the full 16-bit value with the LSB equal to 100V, yielding a total range of 0 to +6.55V. To calculate the supply voltage, multiply the 16-bit unsigned integer by 100V. Internally measured laser bias current is represented as a 16-bit unsigned integer with the current defined as the full 16-bit value with the LSB equal to 2A, yielding a total range of 0 to 131 mA. To calculate the laser bias current, multiply the 16-bit unsigned integer by 2A. GO2929 1310nm MSA Compatible Optical Transceiver Data Sheet 56644 - 1 June 2011 13 of 26 Internally measured Tx and Rx optical power are represented as a 16-bit unsigned integer with the power defined as the full 16-bit value with the LSB equal to 0.1W, yielding a total range of 0 to 6.5535mW (~ -40 to +8.2dBm). To calculate the Tx and Rx optical power, multiply the 16-bit unsigned integer by 0.1W.
