Serial Communication Protocol All Finisar optical GBICs are ‘Module Definition “4”’ and support the 2 wire serial communication protocol outlined in the GBIC Specification 1. These GBICs use an Atmel AT24C01A 128 byte E2PROM (with an address of 1010000X). For details on interfacing with the E2PROM, see the Atmel data sheet titled “AT24C01A/02/04/08/16 2Wire Serial CMOS E2PROM.”5 All Finisar optical GBICs also incorporate a microcontroller that monitors system parameters such as laser current, laser temperature, and, in the case of 13xx/14xx/15xx/16xx nm parts, transmitted power. For a complete description of how to use Finisar’s extended features, see Finisar’s Application Note AN-20304. CAUTION: The microcontroller implements the Philips I2C protocol including clock stretching. For details, consult the Philips I2C-Bus Specification. Clock stretching allows a fast master to communicate with a slow slave device, and it requires that the host monitor the clock line every time it releases the line high. If a host does not implement clock stretching (drives the bus blind), it must run the clock below 8kHz, so that Finisar’s microcontroller has time to process instructions. If clock stretching is supported, the clock may be run at up to 100kHz. I2C Timing Requirements Parameter Atmel I2C Clock Rate Symbol Catmel Min 0 Typ Max 100,000 Units Notes/Conditions Hz Bus can be driven blind. Finisar Microcontroller I2C Clock Rate C1 10 100,000 Hz Host must support clock stretching. Microcontroller times out if C < 10Hz. Finisar Microcontroller I2C Clock Rate C2 10 8000 Hz Bus can be driven blind. Microcontroller times out if C < 10Hz. Table 9.
