Figure 2. Standby Mode
Standby Mode
In standby mode, the filter and output amplifiers are off,
and only the active video detect circuit is operational.
Quiescent current consumption is approximately 7A
(Figure 2). The active video detect circuit checks
whether sync is present on the CVBSIN signal. If no
sync is detected, the device remains in standby mode.
Active-Detect Mode
The active video detect circuit slices the CVBSIN signal
at 4.7% of the power supply (155mV for a 3.3V supply).
If the transitions occur at a rate of 14.3kHz or higher, a
video signal is present. When the MAX9513 detects a
video signal with sync at the CVBSIN input, the control
logic enters the active-detect mode and enables the
load-sense circuitry (Figure 3). The supply current is
typically 17A.
If an output load is not connected to any amplifier, the
MAX9513 remains in active-detect mode. Eight times per
second, each load-sense circuit checks for a load by
connecting an internal 15k
Ω pullup resistor to the output
for 1ms. If the output is pulled up, no load is present. If
the output stays low, a load is connected.
