FSR CDA-4/6 - Manual (Page 3)

INTRODUCTION
The all new CDA - 4 and 6 are ultra high resolution, ultra high bandwidth 1 x 4
and 1 x 6 computer distribution amplifi ers suitable for applications requiring the
highest possible video quality. The output channels on each unit
have cable equalization permiting long cable runs while maintaining excellent
signal integrity for even the highest video resolutions.
Not only do these two units have over 375 MHz of bandwidth but they also have
the FSR computer compatible sychronizing circuitry to ensure a rock stable
video image at any resolution and signal level.
The outputs are equalized to maintain excellent signal integrity for all video
resolutions. Cable runs of up to 150 feet are possible with 162 MHz of full
amplitude bandwidth and 0.5 dB peaking. Peaking remains below 0.5 dB even
at 0.2V p-p input level.
Channel-channel matching (red vs green/red vs blue) response is extremely
fl at. About 0.25 dB out to 320MHz
It will restore the bandwidth of 150' of the design cable to 162 MHz, with a
0.5 dB fl atness to 143MHz at full 0.7V p-p amplitude. At 0.2V p-p, these
fi gure become 305MHz and 256MHz respectively
This means that the signal you feed into the CDA-4 or CDA-6 will arrive at
the far end of the cable with an almost immeasurable amount of loss and no
distortion due to peaking effects.
