FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The HDA-1811 is a reclocked high definition serial
digital video distribution amplifier. The HDA-1811
has one input, and 4 outputs, with automatic
equalization for up to 110 meters of cable (Belden
1694a) at 1.485 or 1.485/1.001 Gbps. The amplifier
offers signal presence detection and remote
reporting, and includes reclocking, providing an
additional level of signal integrity in long cable
length applications. While primarily designed for
distribution of HD serial digital signals (SMPTE
292M), the HDA-1811 automatically detects non-
HD signals and distributes them without reclocking.
This multi-rate feature makes the HDA-1811 ideal
for applications where HD and SD signals may
coexist. The HDA-1811 is designed for use in the
DENSITÉ
frame.
