(DENSITÉ) SERIES
DESCRIPTION
The SDA-1141 is a reclocked serial digital video
distribution amplifier with analog video
monitoring outputs. The SDA-1141 handles V-bit
and provides 5 reclocked outputs and 4
copmposite analog video monitoring outputs; it
also provides automatic equalization for up to 350
meters of cable (Belden 1694A), and signal
presence detection and remote reporting. The
SDA-1141 includes reclocking, providing an
additional level of signal integrity in longcable
length applications. The SDA-1141 supports serial
digital video (SMPTE 259M) at 270 Mbps. The SDA-
1141 is designed to be used in a DENSITÉ frame. A
"single" or "double" rear connector panel is
required.
