General Description
Packaged in a 1mm x 1mm UCSP™ with 4 bumps, the
MAX9519 is an ultra-small standard-definition video filter amplifier with automatic shutdown.
The automatic shutdown circuitry eliminates the need
for a shutdown control. This feature provides intelligent
power management by disabling the filter and output
amplifier in the absence of a video input signal and/or
an output video load. At shutdown, the device consumes only 1.8µA.
The MAX9519 features an internal reconstruction filter
that smooths the steps and reduces the spikes on the
video signal from the video digital-to-analog converter
(DAC). The reconstruction filter typically has ±1dB
passband flatness to 9MHz and typically 48.5dB of
attenuation at 27MHz.
The video input to the MAX9519 can be directly connected to the DAC output. The MAX9519 has an internal fixed gain of 4V/V and expects a nominal full-scale
video input signal of 0.5V
P-P
. The MAX9519 is specified
to operate over the -40°C to +125°C automotive temperature range.

Detailed Description
The MAX9519 is an ultra-small, standard-definition video
filter amplifier with automatic shutdown. Automatic shutdown circuitry provides intelligent power management
by disabling the filter and output amplifier in the
absence of an input video signal and/or output load.
Figure 1 shows automatic shutdown.
An internal reconstruction filter smooths the steps and
reduces the spikes on the video signal from the video
digital-to-analog converter. The reconstruction filter typically has ±1dB passband flatness to 9MHz and typically 48.5dB of attenuation at 27MHz. The MAX9519
has an internal fixed gain of 4V/V and expects a nominal full-scale video input signal of 0.5V
P-P
.
Automatic Shutdown
The MAX9519 automatic shutdown circuitry reduces
power consumption when there is no active video input
signal or an output load. In shutdown, the supply current is reduced to 1.8µA. The video amplifier only turns
on when both an active video input signal and an output load are present.
The MAX9519 slices the IN signal at 2.4% of the power
supply (80mV for a 3.3V supply). If the transitions occur
at a rate of 7.3kHz or higher, a video signal is present.
When the MAX9519 detects a video signal with sync at
the input, the control logic enters the active-detect mode
and enables the load sense circuitry (Figure 2). The supply current increases from 1.8µA to 5.4µA typically.
If an output load is not connected to the amplifier, the
MAX9519 remains in active-detect mode. Eight times
per second, the load-sense circuit checks for a load by
connecting an internal 15kΩ 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.
If the input video signal is present and a load is connected to the output, the filter and amplifier turn on and
remain on until the output load is disconnected.
Automatic shutdown intelligently reduces the supply
current based on the input signal presence and output
loading (Figure 3).
When the amplifier is on, it continually checks if the
load has been disconnected by detecting if the amplifier output is sourcing current during a horizontal line
time. If no sourcing current is detected within one horizontal line time (approximately 64µs), the load has
been disconnected and the amplifier returns to activedetect mode. If, at any time, the input video signal is
removed, the MAX9519 returns to standby mode.

Input
The MAX9519 video input should be directly connected
to the output of the video current DAC. DC-coupling
ensures that the input signal is ground referenced such
that the sync tip of the composite video signal is within
25mV of ground. Any standard-definition video signal
can be applied to the input as long as the signal is
between ground and 0.525V when VDD= 2.7V.
Video Reconstruction Filter
The filter passband (±1dB) is typically 9MHz, which
makes the device suitable for standard-definition video
signals from all sources (e.g., broadcast and DVD).
Broadcast video signals are channel limited: NTSC signals have 4.2MHz bandwidth, and PAL signals have
5MHz of bandwidth. Video signals from a DVD player,
however, are not channel limited; so the bandwidth of
DVD video signals approaches the Nyquist limit of
6.75MHz. Recommendation: ITU-R BT.601-5 specifies
13.5MHz as the sampling rate for standard-definition
video. Therefore, the maximum bandwidth of the signal
is 6.75MHz. To ease the filtering requirements, most
modern video systems over sample by two times,
clocking the video current DAC at 27MHz.
Output
The MAX9519 output expects to drive a DC-coupled
load to ground. The amplifier output stage needs about
300mV of headroom from either supply rail. The device
has an internal level shift circuit that positions the sync
tip at approximately 300mV at the output.
Applications Information
Power-Supply Bypassing and Ground
The MAX9519 operates from a single-supply voltage
down to 2.7V, allowing for low-power operation. Bypass
VDDto GND with a 0.1µF capacitor. Place all external
components as close as possible to the device.
