Figure 41. ADA4830-1 Driving an ADV7180 Video Decoder
The ADA4830-1 and ADA4830-2 are differential receivers whose
overall performance is independent of the transmitter IC used
and whether the transmission line is ac-coupled or dc-coupled.
The ADA4830-1 and ADA4830-2 are specifically designed to
perform as differential line receivers. The circuit in Figure 41
shows a detailed schematic of the ADA4830-1 and the ADV7180
configured for this function. The signal is received differentially
relative to the common of the source circuitry, and that voltage
is exactly reproduced with an attenuating gain of 0.50 V/V. This
is designed to keep the video signal within the allowed range of
the video decoder, which is typically 1 V p-p or less.
The common-mode rejection vs. frequency, shown in Figure 14,
typically 65 dB at low frequencies, enables the recovery of video
signals in the presence of large common-mode noise. The high
input impedance permits the ADA4830-1 and ADA4830-2 to
operate as a bridging amplifier across low impedance terminations
with negligible loading.
