B1 Page 2 Finisar FTR-1519-V2 Extended GBIC Product Specification – November 2007 II. Electrical Power Interface Finisar FTR-1519-V2 GBICs have an extended power supply voltage range of 3.15V to 5.5V as described in Table 2. They are compatible with both 5V and 3.3V systems. The GBIC specification calls for a range of only 4.75V to 5.25 volts. The 6V maximum voltage is not allowed for continuous operation, however, TX_FAULT and TX_DISABLE circuitry in Finisar GBICs will function at 6V.

Referenced to GND Table 2. Electrical power interface III. Low Speed Signals RX_LOS, TX_DISABLE, and TX_FAULT are TTL signals as described in Table 3. MOD_DEF(1) (SCL) and MOD_DEF(2) (SDA) are open drain CMOS signals (see section VI, “Serial Communication Protocol”). Both MOD_DEF(1) and MOD_DEF(2) must be pulled up to host_Vcc. If host_Vcc is 3.3V, then they must be pulled to 3.3V. If host_Vcc is 3.3V, do not pull the MOD_DEF pins to 5V.

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 1300nm/1550nm parts, transmitted power. The microcontroller I2C address is 1010111X, so it won’t conflict with the AT24C01A. For a complete description of how to use Finisar’s extended features, see Finisar’s Application Note AN-2025: “Using the Finisar GBIC I2C Test/Diagnostics Port.”4 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.

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. I2C timing requirements © Finisar Corporation November 16, 2007 Rev.
