The HDMP-1032A/1034A chipset
was designed for ease of use
and flexibility. The customer can
tailor the use of this product
through the configuration of the
link based on specific system re-
quirements and application needs.
Typical applications range from
backplane serialization and bus
extension to cellular base stations.

For digital video transmission,
simplex links are common. The
HDMP-1032A/1034A chipset can
transmit 16 bits of parallel data
in standard or broadcast simplex
mode (Figures 1a, 1b).
B) 16 BIT BROADCAST TRANSMISSION
If the bus is 32 bits wide, the
HDMP-1032A/1034A chipset is
capable of sending this data word
as two separate word segments
with the use of an external mux
and demux as shown in Figure
1c. In this mode, the transmitter
and receiver use the FLAG bit to
indicate the first or second word
segment. The HDMP-1032A/

1034A chipset may also be con-
figured in full duplex to achieve a
32 bit wide bus extension. In ad-
dition, 32 bit wide data can be
transmitted over two parallel se-
rial lines as shown in Figure 1d.

Low latency bus extension of
a 16 bit wide data bus may be
achieved using the full duplex
configuration (Figure 1e). In this
mode, link startup is achieved
by exchange of control words.
