Typical Applications

The HDMP-1022/1024 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 his

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-

1022/1024 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-1022/1024

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

(Figure 19). The HDMP-1022/

1024 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-1022/1024 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.
