Compensation
The MAX5018 provides an external compensation input
(COMP) for the reference buffer amplifier. To use this
pin correctly, connect a capacitor between COMP and
V
EE
, as shown in Figure 1. Keep lead lengths as short
as possible. Use a large capacitor (0.01μF) if the refer-
ence is to be kept as a constant. The capacitor’s value
determines the amplifier’s bandwidth. If reference mod-
ulation is required, smaller capacitance values can be
used to achieve up to a 1MHz bandwidth.
Data Inputs and V ideo Controls
The MAX5018 has standard, single-ended data inputs.
The inputs are registered to produce the lowest differ-
ential data-propagation delay (skew) to minimize glitch-
ing. Also, four video-control inputs generate composite
video outputs: sync, blank, bright, and reference white
(force high). Feedthrough control is also provided. All
of the controls and data inputs are ECL compatible. In
addition, all have internal pulldown resistors to leave
them at a logic low so the pins are inactive when not
used. This feature is useful if the devices are applied as
standard DACs without the need for video controls, or if
fewer than eight bits are used.
The MAX5018 is usually configured in synchronous
mode. In this mode, the controls and data are synchro-
nized to prevent pixel dropout. This reduces screen-
edge distortions and provides the lowest output noise
while maintaining the highest conversion rate. With the
FT control open (low), each rising edge of the convert
clock (CONV) latches decoded data and control values
into a D-type internal register. The switched-current
