9910DA-AV-EQ Functional Description
Figure 1-1 shows a functional block diagram of the 9910DA-AV-EQ. With
the appropriate rear module, the 9910DA-AV-EQ can provide up to eight DA
analog video outputs and a looping input where desired.
9910DA-AV-EQ Input/Output Formats
The 9910DA-AV-EQ provides the following inputs and outputs:
•Inputs:
•ANALOG VIDEO IN –coaxial analog composite video input
•Outputs:
•ANALOG OUT (1-8) –up to eight analog composite outputs
•LOOP OUT –where enabled using card jumper and with appropriate
rear module, the card provides a hi-Z (unterminated) looped output
of the input
Input Differential/Single-Ended Select
Using an on-card jumper, the 9910DA-AV-EQ can float the input shield
connection from ground, and use both the + and shield connections as a
differential pair, thereby providing much improved common-mode noise
rejection that minimizes the effects of ground-loop noise and other issues. A
single-ended jumper position provides normal operation where the shield
connection is tied to chassis ground. (Default position is typical single-ended
operation with shield lead tied to chassis GND.)
Input Loop/Termination Select
Using an on-card jumper, the 9910DA-AV-EQ can terminate the input into a
Zo= 75Ωor offer a hi-Z input with the input available as a looped output.
(Default position is 75Ωterminated position with no looping output.)
Input AC/DC Coupling Select
Using an on-card jumper, the 9910DA-AV-EQ can use input capacitive
coupling or full DC coupling to the card active circuitry. Low-frequency
cut-off of the single coupling capacitor is such that normal video bandwidth is
not affected. Where AC coupling is used, the Video Clamp feature of this card
should also be used to restore correct DC levels with APL (active picture
level) changes. (Default position is DC-coupled.)

Notes: 1. Signal connections shown depicts full input/output capability.
Practical input/output signal availability is determined by Rear I/O Module used. Refer to 9910DA-AV-EQ Rear I/O Modules (p. 2-6) for more information.
2. Some Rear I/O Modules allow only typical single-ended input
operation (shield conductor of input BNC tied to GND). Also, these rear module can only be used when input termination (non-looping) is selected using the card jumper. Not all rear modules provide the looping output connection. See Chapter 2, Installation for more information.

Video Clamping Select
The card is equipped with clamping select jumpers. Clamping can be set on or
off. When set to on, slow and fast clamping can also be selected using another
jumper. Slow clamping is stable, while fast clamping is optimized to respond
to fast changes in APL where required. (Default control setting is on; slow
setting.) Clamping can help eliminate hum on the output signal in cases where
poor grounding or other signal routing issues are present on the input.
(Clamping is intended for use only with SD black-burst (bi-level) sync
signals and may result in loss of output if used with HD tri-level input
signals.)
EQ Adjust
(See Figure 1-2.) A card-edge trimmer potentiometer allows tailoring the card
high-frequency response to compensate for reactive losses in long cable
lengths. Depending on the purpose of the distributed signal (i.e., sync
distribution or monitor/source feed), the EQ setting can be optimized for sync
edge or frequency response (respectively). (Default control setting is null (full
CCW control position) adjustment.) A card jumper sets the EQ adjust curve
as Normal or Max. Normal setting provides normal increased gain at the
high-end of the passband. Max setting provides cascaded high-end boost with
a steeper compensation curve.
Figure 1-2 EQ Adjust Response Curves
Gain Adjust
A card-edge trimmer potentiometer allows gain adjustment of for the DA
outputs (the default setting is unity gain). Gain adjustment is downstream of
the EQ adjustment stage such that gain adjustment and EQ optimization have
no effect on each other’s optimized settings and are independent. Regardless
of most distribution purposes, gain adjustment (if necessary) should provide
for linear operation with 100 IRE at the destination. (Default control setting is
unity gain.)
