The AFCT-57F5ATMZ is a multi-rate 1310 nm transceiver which ensures compliance with FC-PI-5 16 GFC, 8 GFC and 4 GFC specifications. Per the requirements of 16 GFC, an internal clock and data recovery circuit CDR is present on the electrical output of this transceiver. This CDR will lock at 14.025Gb/s 16 GFC but must be bypassed for operation at 8.5Gb/s 8 GFC and 4.25Gb/s 4 GFC , accomplished by using Rate Select inputs to configure transmit and receive sides. Transmitter and receiver can operate at different data rates, as is often seen during Fibre Channel speed negotiation. Digital diagnostic monitoring information DMI is present in the AFCT-57F5ATMZ per the requirements of SFF-8472, providing real time monitoring information of transceiver laser, receiver and environment conditions over a SFF8431 2-wire serial interface.

The TOSA contains a 1310nm Distributed Feedback Laser DFB light source with integral light monitoring function and imaging optics to assure efficient optical coupling to the LC connector interface. The TOSA is driven by a laser driver IC, which uses the differential output from an integral Tx equalization stage to modulate and regulate DFB optical power.

Receiver Section The receiver section includes a Receiver Optical SubAssembly ROSA , pre-amplification and post-amplification circuit, Clock and Data Recovery Circuit and an electrical output stage with variable emphasis controls. The ROSA, containing a high speed PIN detector, pre-amplifier and imaging optics efficiently couple light from the LC connector interface and perform an optical to electrical conversion. The resulting differential electrical signal passes through a post amplification circuit and into a Clock and Data Recovery circuit CDR for cleaning up accumulated jitter. The resulting signal is passed to a high speed output line driver stage with variable, I2C-bus controlled, emphasis settings allowing the host to optimize signal characteristics between the SFP and host ASIC. Note the Rx CDR is engaged only with Rx_RATE=high 16 GFC and bypassed with Rx_RATE=low 8G/4G . Digital Diagnostics The AFCT-57F5ATPZ is compliant to the Diagnostic Monitoring Interface DMI defined in document SFF-8472. These features allow the host to access, via I2C-bus, real time diagnostic monitors of transmit optical power, received optical power, temperature, supply voltage and laser operating current. Low Speed Interfaces Conventional low speed interface I/Os are available as defined in documents SFF-8074 and SFF-8431 to manage coarse and fine functions of the optical transceiver. On the transmit side, a Tx_DISABLE input is provided for the host to turn on and off the outgoing optical signal. A transmitter rate select control input, Tx_RATE, is provided to configure the transmitter stages for 16 GFC, 8 GFC or 4 GFC operation logic HIGH , reserved for 16 GFC, logic LOW , reserved for 8 GFC and 4 GFC .
