On-Chip Referenc e Circ uit
The MAX1429 incorporates an on-chip 2.5V, low-drift
bandgap reference. This reference potential establish-
es the full-scale range for the converter, which is nomi-
nally 2.2V
P-P
differential. The internal reference
potential is not accessible to the user, so the full-scale
range for the MAX1429 cannot be externally adjusted.
Figure 3 shows how the reference is used to generate
the common-mode bias potential for the analog inputs.
The common-mode input bias is set to one diode
potential above the bandgap reference potential, and
so varies over temperature.
Cloc k Inputs (CLK P, CLK N)
The differential clock buffer for the MAX1429 has been
designed to accept an AC-coupled clock waveform.
Like the signal inputs, the clock inputs are self-biasing.
In this case, the common-mode bias potential is 2.4V
and each input is connected to the reference potential
through a 1k
resistor. Consequently, the differential
input resistance associated with the clock inputs is
2k
. While differential clock signals as low as 0.5V
P-P
may be used to drive the clock inputs, best dynamic
performance is achieved with clock input voltage levels
of 2V
P-P
to 3V
P-P
. J itter on the clock signal translates
directly to jitter (noise) on the sampled signal.
Therefore, the clock source should be a low-jitter (low-
phase noise) source. See the
Applications Information
section for additional details on driving the clock inputs.
S ystem T iming Requirements
Figure 4 depicts the timing relationships for the signal
input, clock input, data output, and DAV output. The
variables shown in the figure correspond to the various
timing specifications in the
Electrical Characteristics
table. These include:
t
DAT
: Delay from the rising edge of the clock until the
50% point of the output data transition
t
DAV
: Delay from the falling edge of the clock until the
50% point of the DAV rising edge
t
DNV
: Time from the rising edge of the clock until data
is no longer valid
