MAXIM MAX9515 Technical data

General Description

Packaged in a 1mm x 1mm UCSP™ with 4 bumps, the
MAX9515 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 only con­sumes 5µA.

The MAX9515 features an internal reconstruction filter
that smoothes 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 50dB of atten­uation at 27MHz.

The video input to the MAX9515 can be directly con­nected to the DAC output. The MAX9515 has an inter­nal fixed gain of 2V/V and expects a nominal full-scale
video input signal of 1V

P-P

. The MAX9515 is specified
to operate over the -40°C to +125°C automotive tem­perature range.

Detailed Description

The MAX9515 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.

An internal reconstruction filter smoothes 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 50dB of attenuation at 27MHz. The MAX9515 has
an internal fixed gain of 2V/V and expects a nominal

Automatic Shutdown

The MAX9515 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 5µA. The video amplifier only turns
on when both an active video input signal and an out­put load are present.

The MAX9515 slices the IN signal at 4.7% of the power
supply (155mV for a 3.3V supply). If the transitions
occur at a rate of 7.3kHz or higher, a video signal is
present. When the MAX9515 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 5µA to
9µA typically.

If an output load is not connected to the amplifier, the
MAX9515 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 MAX9515 returns to standby mode.

Input

The MAX9515 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
50mV of ground. Any standard-definition video signal
can be applied to the input as long as the signal is
between ground and 1.05V 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 MAX9515 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 MAX9515 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.
