ABCU-57xxxxZ Family
10/100/1000BASE-T 1.25 GBd Small Form Pluggable
Low Voltage (3.3 V) Electrical Transceiver over Category 5 Cable
Data Sheet
Description
The ABCU-57xxxxZ family of electrical transceivers from
Avago Technologies offer full-duplex throughput of 1000
Mbps by transporting data over shielded and unshielded
twisted pair category 5 cable with 5-level PAM (Pulse
Amplitude Modulation) signals.
The Avago Technologies 1000BASE-T module takes sig-
nals from both the twisted pair category 5 cable and the
SerDes interface. Pin count overhead between the MAC
and the PHY is minimized, and Gigabit Ethernet opera-
tion is achieved with maximum space savings.

Installation
The ABCU-57xxxxZ family can be installed in or removed
from any MultiSource Agreement (MSA) compliant Small
Form Pluggable port whether the host equipment is
operating or not. The module is simply inserted, small
end first, under finger-pressure. Controlled hot-plugging
is ensured by design and by 3-stage pin sequencing at
the electrical interface to the host board. The module
housing makes initial contact with the host board EMI
shield, mitigating potential damage due to ElectroStatic
Discharge (ESD). The module pins sequentially contact
the (1) Ground, (2) Power, and (3) Signal pins of the host
board surface mount connector. This printed circuit board
card-edge connector is depicted in Figure 2.

Serial Identification (EEPROM)
The ABCU-57xxxxZ family complies with an industry stan-
dard MultiSource Agreement that defines the serial identi-
fication protocol. This protocol uses the 2-wire serial CMOS
EEPROM protocol of the ATMEL AT24C01A or equivalent.
The contents of the ABCU-57xxxxZ family serial ID memory
are defined in Table 10 as specified in the SFP MSA.
Controller and Data I/O
Data I/Os are designed to accept industry standard dif-
ferential signals. In order to reduce the number of passive
components required on the customer’s board, Avago
Technologies has included the functionality of the trans-
mitter bias resistors and coupling capacitors within the
module. The transceiver is compatible with an “ac-coupled”
configuration and is internally terminated. Figure 1 depicts
the functional diagram of the ABCU-57xxxxZ family of
transceivers. 100-ohm resistor shown at RX_LOS in Figure
1 refers to ABCU-573xxxZ configuration.
Caution should be taken into account for the proper inter-
connection between the supporting Physical Layer integrat-
ed circuits and the ABCU-57xxxxZ family of transceivers.
Figure 4 illustrates the recommended interface circuit.
Several control data signals and timing diagrams are imple-
mented in the module and are depicted in Figure 6.

Evaluation Kit
To help you in your preliminary transceiver evaluation,
Avago Technologies offers a 1.25 GBd Gigabit Ethernet
evaluation board. This board will allow testing of the
electrical parameters of transceiver. Please contact your
local Field Sales representative for availability and order-
ing details.
Electrostatic Discharge (ESD)
There are two conditions in which immunity to ESD dam-
age is important. Table 1 documents our immunity to
both of these conditions. The first condition is during han-
dling of the transceiver prior to insertion into the trans-
ceiver port. To protect the transceiver, it is important to
use normal ESD handling precautions. These precautions
include using grounded wrist straps, work benches, and
floor mats in ESD controlled areas. The ESD sensitivity of
the ABCU-57xxxxZ is compatible with typical industry
production environments.
The second condition is static discharges to the exterior
of the host equipment chassis after installation. To the
extent that the RJ45 connector interface is exposed to the
outside of the host equipment chassis, it may be subject
to system-level ESD requirements. The ESD performance
of the ABCU-57xxxxZ exceeds typical industry standards.
Regulatory Compliance
See Table 1 for transceiver Regulatory Compliance perfor-
mance. The overall equipment design will determine the
certification level. The transceiver performance is offered
as a figure of merit to assist the designer.
Immunity
Equipment hosting the ABCU-57xxxxZ modules will be
subjected to radio-frequency electromagnetic fields in
some environments. The transceivers have excellent im-
munity to such fields due to their shielded design.

Electromagnetic Interference (EMI)
Most equipment designs utilizing these high-speed trans-
ceivers from Avago Technologies will be required to meet
the requirements of FCC in the United States, CENELEC
EN55022 (CISPR 22A) in Europe and VCCI in Japan.
The metal housing and shielded design minimize the
EMI challenge facing the host equipment designer. These
transceivers provide superior EMI performance. This
greatly assists the designer in the management of the
overall system EMI performance.
Caution
There are no user serviceable parts nor any maintenance
required for the ABCU-57xxxxZ. Tampering with or
modifying the performance will result in voided product
warranty. It may also result in improper operation of the
ABCU-57xxxxZ circuitry, and possible overstress of the
RJ 45 connector. Device degradation or product failure
may result. Connecting the module to a non-approved
1000BaseT module, operating above the recommended
absolute maximum conditions or operating the ABCU-
57xxxxZ in a manner inconsistent with its design and
function may result in hazardous radiation exposure and
may be considered an act of modifying or manufacturing
an electrical module product.
Flammability
The ABCU-57xxxxZ electrical transceiver housing is
made of metal and high strength, heat resistant, chemi-
cally resistant, and UL 94V-0 flame retardant plastic.
