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.
