AV02-4387EN 43 Avago Technologies
Isolated Video Interface
Description
This circuit, with the HCPL-4562
Wideband Analog/Video Optocou-
pler, is optimized for video signal
coupling. The peaked response of
the detector circuit helps extend the
frequency range over which the gain
is relatively constant. The number of
gain stages, the overall circuit topol-
ogy, and the dc bias points are all
chosen to maximize the bandwidth.
Performance of Circuit
• Typical bandwidth: 15 MHz
• Typical Gain variation: ­1.1 dB at 5
MHz with reference at 0.1 MHz
• Isolation Mode Rejection: 122 dB
at 120 Hz
Benefits
• Cost­effective, high perfor mance
video interface circuit
