Functional I/O
The AFBR-571 Z accepts industry standard differential
signals such as LVPECL and CML within the scope of the
SFP MSA. To simplify board requirements, transmitter
bias resistors and ac coupling capacitors are
incorporated, per SFF-8074i, and hence are not required
on the host board. The module is AC-coupled and
internally terminated.
Figure 3 illustrates a recommended interface circuit to
link the AFBR-571 Z to the supporting Physical Layer
integrated circuits.
Timing diagrams for the MSA compliant control signals
implemented in this module are depicted in Figure 6.
The AFBR-571 Z interfaces with the host circuit board
through twenty I/O pins (SFP electrical connector)
identified by function in Table 2. The AFBR-571 Z high
speed transmit and receive interfaces require SFP MSA
compliant signal lines on the host board. The Tx_Disable,
Tx_Fault, and Rx_LOS lines require TTL lines on the host
board (per SFF-8074i) if used. If an application chooses
not to take advantage of the functionality of these pins,
care must be taken to ground Tx_Disable (for normal
operation).

Digital Diagnostic Interface and Serial Identification
(EEPROM)
The entire AFBR-571 Z family complies with the SFF-
8074i SFP specification. The AFBR-5715Z family further
complies with SFF-8472, the SFP specification for Digital
Diagnostic Monitoring Interface. Both specifications can
be found at http://www.sffcommittee.org.
The AFBR-571 Z features an EEPROM for Serial ID, which
contains the product data stored for retrieval by host
equipment. This data is accessed via the 2-wire serial
EEPROM protocol of the ATMEL AT24C01A or similar, in
compliance with the industry standard SFP Multi-Source
Agreement. The base EEPROM memory, bytes 0-255 at
memory address 0xA0, is organized in compliance with
SFF-8074i. Contents of this serial ID memory are shown
in Table 10.
