Functional Data I/O

The AFBR-57R5APZ interfaces with the host circuit board

through twenty I/O pins (SFP electrical connector) iden-

tiﬁed by function in Table 2. The board layout for this

interface is depicted in Figure 6.

The AFBR-57R5APZ high speed transmit and receive

interfaces require SFP MSA compliant signal lines on Regulatory Compliance

The AFBR-57R5APZ complies with all applicable laws

resistors and ac coupling capacitors are incorporated into

the SFP transceiver module (per SFF-8074i) and hence are

not required 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).

and regulations as detailed in Table 1. Certiﬁcation level

is dependent on the overall conﬁguration of the host

equipment. The transceiver performance is oﬀered as a

ﬁgure of merit to assist the designer.

Electrostatic Discharge (ESD)

The AFBR-57R5APZ is compatible with ESD levels found

in typical manufacturing and operating environments

as described in Table 1. In the normal handling and

operation of optical transceivers, ESD is of concern in two

circumstances.

Figure 2 depicts the recommended interface circuit to

link the AFBR-57R5APZ to supporting physical layer ICs.

Timing for MSA compliant control signals implemented

in the transceiver are listed in Figure 4.

Application Support

The ﬁrst case is during handling of the transceiver prior

to insertion into an SFP compliant cage. To protect the

device, it’s important to use normal ESD handling pre-

cautions. These include use of grounded wrist straps,

work-benches and floor wherever a transceiver is

handled.

An Evaluation Kit and Reference Designs are available to

assist in evaluation of the AFBR-57R5APZ. Please contact

your local Field Sales representative for availability and

ordering details.

Ordering Information

The second case to consider is static discharges to the

exterior of the host equipment chassis after installation.

If the optical interface is exposed to the exterior of host

equipment cabinet, the transceiver may be subject to

system level ESD requirements.

Please contact your local ﬁeld sales engineer or one of

Avago Technologies franchised distributors for ordering
