HBCU-5710R
1000BASE-T Small Form Pluggable Low Voltage (3.3 V) Electrical
Transceiver over Category 5 Unshielded Twisted Pair Cable
Data Sheet
Description
The HBCU-5710R electrical transceiver from Avago Tech-
nologies offers full duplex throughput of 1000 Mb/s by
transporting data over unshielded twisted pair category
5 cable with 5-level PAM (Pulse Amplitude Modulation)
signals. The Avago Technologies 1000BASE-T module
takes signals 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
operation is achieved with maximum space savings.

Module Diagrams
Figure 1 illustrates the major functional components
of the HBCU-5710R. The 20-pin connection diagram of
module printed circuit board of the module is shown in
Figure 2. Figure 3 depicts the pin assignment of the MDI
(RJ45 jack).
Figure 7 depicts the external configuration and dimen-
sions of the module.
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-cou-
pled” configuration and is internally terminated. Figure
1 depicts the functional diagram of the HBCU-5710R.
Caution should be taken into account for the proper
interconnection between the supporting Physical Layer
integrated circuits and the HBCU-5710R. Figure 4 illus-
trates the recommended interface circuit.
Several control data signals and timing diagrams are imple-
mented in the module and are depicted in Figure 6.
Installation
The HBCU-5710R 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, un-
der 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 Electro-Static 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 HBCU-5710R complies with an industry standard
MultiSource Agreement that defines the serial identifica-
tion protocol. This protocol uses the 2-wire serial CMOS
EEPROM protocol of the ATMEL AT24C01A or equivalent.
The contents of the HBCU-5710R serial ID memory are
defined in Table 3 as specified in the SFP MSA.

Reference Designs
Reference designs for the HBCU-5710R electrical trans-
ceiver and the HDMP-1636A physical layer IC are avail-
able to assist the equipment designer. Figure 4 depicts a
typical application configuration, while Figure 5 depicts
the MSA power supply filter circuit design. Please con-
tact your local Field Sales engineer for more information
regarding application tools.

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 of the HBCU-
5710R 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.
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.
Electrostatic Discharge (ESD)
There are two conditions in which immunity to ESD
damage is important. Table 1 documents our immunity
to both of these conditions. The first condition is during
handling of the transceiver prior to insertion into the
transceiver port. To protect the transceiver, it is impor-
tant 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 HBCU-5710R 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 con-
nector 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 HBCU-5710R
exceeds typical industry standards.
Flammability
The HBCU-5710R electrical transceiver housing is made
of metal and high strength, heat resistant, chemi-
cally resistant, and UL 94V-0 flame retardant plastic.
Caution
There are no user serviceable parts nor any maintenance
required for the HBCU-5710R. Tampering with or modi-
fying the performance of the HBCU-5710R will result in
voided product warranty. It may also result in improper
operation of the HBCU-5710R circuitry, and possible
overstress of the RJ 45 connector. Device degradation
or product failure may result. Connection of the HBCU-
5710R to a non-approved other 1000BASE-T module,
operating above the recommended absolute maximum
conditions or operating the HBCU-5710R 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.
Immunity
Equipment hosting the HBCU-5710R modules will be sub-
jected to radio-frequency electromagnetic fields in some
environments. The transceivers have good immunity to
such fields due to their shielded design.
