MAX107
designed for single-ended, low-phase noise sine-wave
clock signals with as little as 500mVp-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 (500mVp-p clock signal
amplitude) to +10dBm (2Vp-p clock signal amplitude).
The MAX107 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 MAX107 clock
also allows these inputs to be driven by LVDS-, ECL- or
PECL-compatible input levels, ranging from 500mVp-p
to 2Vp-p (Figure 6).
Timing Requirements
The MAX107 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
demultiplexed outputs are presented in dual 6-bit two’s
complement format with two consecutive samples in
the primary and auxiliary output ports on the rising
