Description
The HDMP-1012 transmitter and
the HDMP-1014 receiver are used
to build a high speed data link for
point to point communication.
The monolithic silicon bipolar
transmitter chip and receiver chip
are each provided in a standard
aluminum M-Quad 80 package.
From the user’s viewpoint, these
products can be thought of as
providing a “virtual ribbon cable”
interface for the transmission of
data. Parallel data loaded into the
Tx (transmitter) chip is delivered
to the Rx (receiver) chip over a
serial channel, which can be
either a coaxial copper cable or
optical link.
The chip set hides from the user
all the complexity of encoding,
multiplexing, clock extraction,
demultiplexing and decoding.
Unlike other links, the phase-
locked-loop clock extraction
circuit also transparently provides
for frame synchronization - the
user is not troubled with the
periodic insertion of frame
synchronization words. In
addition, the dc balance of the
line code is automatically
maintained by the chip set. Thus,
the user can transmit arbitrary
data without restriction. The Rx
chip also includes a state-machine
controller (SMC) that provides a
startup handshake protocol for
the duplex link configuration.
The serial data rate of the T/R link
is selectable in four ranges (see
tables on page 5), and extends
from 120 Mbits/s up to 1.25
Gbits/s. The parallel data interface
is 16 or 20 bit single-ended ECL,
pin selectable. A flag bit is
available and can be used as an
extra 17th or 21st bit under the
user’s control. The flag bit can
also be used as an even or odd
frame indicator for dual-frame
transmission. If not used, the link
performs expanded error
detection.
The serial link is synchronous,
and both frame synchronization

and bit synchronization are
maintained. When data is not
available to send, the link
maintains synchronization by
transmitting fill frames. Two
(training) fill frames are reserved
for handshaking during link
startup.
User control space is also sup-
ported. If Control Available is
asserted at the Tx chip, the least
significant 14 or 18 bits of the
data are sent and the Rx Control
Available line will indicate the
data as a Control Word.
It is the intention of this data
sheet to provide the design
engineer all of the information
regarding the HDMP-1012/1014
chipset necessary to design this
product into their application. To

Typical Applications
The HDMP-1012/1014 chipset
was designed for ease of use and
flexibility. This allows the
customer to tailor the use of this
product, through the configura-
tion of the link, based on their
specific system requirements and
application needs. Typical
applications range from
backplane and bus extension to
digital video transmission.
Low latency bus extension of a 16
or 20 bit wide data bus may be
achieved using the standard
duplex configuration (see Figure
1d). In full duplex, the HDMP-
1012/1014 chipset handles all of
the issues of link startup, main-
tenance, and simple error
detection.
If the bus width is 32 or 40 bits
wide, the HDMP-1012/1014
chipset is capable of sending the
large data frame as two separate
frame segments, as shown in
Figure 1b. In this mode, called
Double Frame Mode, the FLAG
bit is used by the transmitter and
receiver to indicate the first or
second frame segment. The
HDMP-1012/1014 chipset in
Double Frame Mode may also be
configured in full duplex to
achieve a 32/40 bit wide bus
extension.
For digital video transmission,
simplex links are more common.
The HDMP-1012/1014 chipset
can transmit 16 to 21 bits of
parallel data in standard or
broadcast simplex mode.
Additionally, 32 to 40 bit wide
data can be transmitted over a
single line (in Double Frame
Mode) or two parallel lines, as in
Figure 1c.
