detailed description
white-balance control
White balance in the monochrome mode can be adjusted with either terminal 2 (white-balance analog control)
or with terminals 3 and 4 (white-balance digital controls B and A, respectively). If analog control is selected,
terminals 3 and 4 should be left open and terminal 2 adjusted appropriately (see Figure 1 and Figure 2 forcontrol
characteristics). The white balance is controlled per the following table:

analog inputs RIN, GIN, BIN
The TI TL1593 sample-and-hold circuit is normally the source for these inputs. The source signals should be
ac coupled into the TL1051. Gain control should be used on at least two of the three channels in order to obtain
an optimum balance.
clamp level
Input terminals 9, 10, and 11 (CLPLVLB, CLPLVLG, and CLPLVLR, respectively) should initially be set at
approximately 2 V dc. The levels should then be balanced so that clock feedthrough on terminal 20 (YSW) is
minimized under dark conditions.
multiplexed switching
Input terminals 13, 14, and 15 (SWR, SWG, and SWB, respectively) are the TTL-level signals used to multiplex
the three channels.
clamping and process blanking
Input terminals 16, 17, and 18 (PCL1, PBL, and PCL2) are used for TTL clamp and blank signals. The dark
references are clamped by the PCL1 signal. Unwanted noise in the video signal is eliminated by the PBL signal.
The Y signal can then be reclamped with the PCL2 signal.
Depending on the application, gain and automatic gain control (AGC) may or may not be selected. The following
descriptions cover both selections.
YSW
YSW output (terminal 20): Fast sampling of the video input signals with the TTL multiplex signals generates this
high-bandwidth output without adjustable gain or AGC.
gain and AGC selected
YAGCINinput(terminal21):IfgainorAGCoperationisselected, theYSWoutput(terminal20)shouldbedirectly
connected to YAGCIN.
YAGC output (terminal 22): The multiplexed signal with controllable gain (controlled by the AGCCONT input)
is available at this terminal if terminals 20 (YSW) and 21 (YAGCIN) are connected. If further signal processing
is desired, this terminal should be ac coupled to terminal 23 (YCLAMP).
YCLAMP input (terminal 23): The Y signal from YAGC can be reclamped at this point by applying a wider clamp
pulse to terminal 18 (PCL2).
WCPCONT input (terminal 24): A dc voltage applied to this white clip control input causes the white clip function
to be performed on the Y signal. See Figure 4 for the clip control characteristics.
YALC output (terminal 25): If either AGC or automatic level control (ALC) is selected, the Y signal at this point
should be fed back to either the ALC or AGC block.
YOUT output (terminal 26): The white-clipped Y signal is available at this output.

analog output channels
Terminals 27, 28, and 29 (ROUT, GOUT, and BOUT) are the individual analog output signals used in RGB color
applications. Their gain can be affected by the control voltage applied to terminal 31 (AGCCONT).
AGC section
The AGC amplifier is a high-gain amplifier that requires an appropriate feedback network.
AGCLMT input (terminal 30): A dc voltage applied to this terminal limits the amount of gain for R, G, B, and Y.
AGCCONT input (terminal 31): A dc voltage applied to this terminal sets the gain (see Figure 3). It is also
possible to build a feedback network and obtain AGC action. In this case, the video signal is fed back through
AGCCONT.
REF2V output (terminal 32): This terminal provides a 2-V reference output.
AGCOUT output (terminal 33): This is the output from the AGC block.
AGCDET input (terminal 34): Video from terminal 26 (YOUT) can be applied to this node to obtain feedback
action.
AGCSET input (terminal 35): A dc voltage applied to this terminal sets the gain for AGC action.
gate section
GATEIN input (terminal 38): If a gating function is desired, video from the YOUT output (terminal 26) can be
applied to this terminal.
GATEOUToutput(terminal39):VideoispassedfromGATEINtoGATEOUTifGATE(terminal40)islow. IfGATE
is high, GATEOUT is in the high-impedance state.
GATE input (terminal 40): A TTL signal can be applied to this input to control the active video (see the description
of the GATEOUT terminal above).
ALC section
An amplifier similar to that in the AGC section is available for use as an integrator. If used, a capacitor should
be connected from the ALC-input (terminal 42) to the ALCDRV output (terminal 43). A reset switch is available
at the RESET input (terminal 44). The ALC amplifier is a high-gain amplifier requiring an appropriate feedback
network.

preprocessor interfaces equally well with a TI TMS3471C 2/3-Inch NTSC timer, a TI SN28837 1/2-Inch PAL timer, or a user-defined
timing generator.
