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 sig-
nals 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
VDD to GND with a 0.1F capacitor. Place all external
components as close as possible to the device.
