and are internally buffered with a preamplifier to ensure
proper operation of the converter even with small-
amplitude sine-wave sources. The MAX105 was
designed for single-ended, low-phase noise sine wave
clock signals with as little as 500mV
P-P
amplitude
(-2dBm).
Single-Ended Clock (Sine-Wave Drive)
Excellent performance is obtained by AC- or DC-cou-
pling a low-phase noise sine-wave source into a single
clock input (
Figure 4). Essentially, the dynamic perfor-
mance of the converter is unaffected by clock-drive
power levels from -2dBm (500mV
p-p
clock signal ampli-
tude) to +10dBm (2V
P-P
clock signal amplitude). The
MAX105 dynamic performance specifications are
determined by a single-ended clock drive of -2dBm
(500mVp-p clock signal amplitude). To avoid saturation
of the input amplifier stage, limit the clock power level
to a maximum of +10dBm.
Differential Clock (Sine-Wave Drive)
The advantages of differential clock drive (Figure 5)
can be obtained by using an appropriate balun or
transformer to convert single-ended sine-wave sources
into differential drives. Refer to
Single-Ended Clock
Inputs (Sine-Wave Drive)
for proper input amplitude
requirements.
LVDS, ECL and PECL Clock
The innovative input architecture of the MAX105 clock
also allows these inputs to be driven by LVDS-, ECL-, or
PECL-compatible input levels, ranging from 500mV
p-p
to 2V
p-p
(Figure 6).
Timing Requirements
The MAX105 features a 6:12 demultiplexer, which
reduces the output data rate (including DREADY and
DOR signals) to one-half of the sample clock rate. The
