outputs with automatic equalization for up to 350
meters of cable (Belden 1694A). The amplifier also
offers signal presence detection and remote
reporting. The SDA-1112 includes reclocking,
providing an additional level of signal integrity in
longcable length applications The SDA-1112
supports DVB-ASI 270 Mbps compressed bit
streams as well as serial digital video at bit rates of
143, 177, 270, 360 and 540 Mbps. The SDA-1112
is designed to be used in a DENSITÉ frame. A
single (for 4 outputs) or double (for 9 outputs) rear
connector panel is required.
