The optional 1k
pull-down resistor connected from the
output of the 2:1 mux to the negative power supply (-V
CC
)
results in improved differential gain and phase perfor-
mance (0.02% and 0.01°) at PAL video levels.
Switched Gain Amplifier (CLC431)
As seen from the front page, the CLC431 can also be
configured as a switched-gain amplifier that is similar to
the 2:1 mux. Configuring each of the two CLC431's
amplifiers with different non-inverting gains and tying the
two inputs together (eliminating one of the input-terminat-
ing resistors) allows the CLC431 to switch an input signal
between two different gains.
Inactive Channel Impedances (CLC431)
The impedance that is seen when looking into the output
of a disabled CLC431 is typically represented as
1M
||16pF. The inverting input impedance becomes
very high, essentially open. Therefore, the impedance
presented by a disabled channel is (R
f
+R
g
)||
(R
i
+(1M
||16pF)) as illustrated in Fig. 4. It should also be
noted that any trace capacitance that is associated with
the common output connection will add in parallel to that
presented by the CLC431's inactive channel.

Twisted-Pair Driver.
Twisted-pair cables are used in many applications such
as telephony, video and data communications. The
CLC432's two matched channels make it well suited for
such applications and is illustrated in Fig. 5.
CCD Amplifier.
The CLC432 can easily be configured as 10MSPS CCD
amplifier with DC level shifting as illustrated in Fig 6.
Notice that one of the CLC432's channels buffers the
CCD output while the other channel is configured with
both an inverting DC gain and an AC gain in order to
achieve the overall transfer function shown in Fig. 6.
