Applications Information
CLK Interface
The MAX5874 features a flexible differential clock input
(CLKP, CLKN) with a separate supply (AVCLK) to
achieve optimum jitter performance. Use an ultra-low
jitter clock to achieve the required noise density. Clock
jitter must be less than 0.5psRMS for meeting the speci-
fied noise density. For that reason, the CLKP/CLKN
input source must be designed carefully. The differen-
tial clock (CLKN and CLKP) input can be driven from a
single-ended or a differential clock source. Differential
clock drive is required to achieve the best dynamic
performance from the DAC. For single-ended opera-
tion, drive CLKP with a low-noise source and bypass
CLKN to GND with a 0.1F capacitor.
Figure 5 shows a convenient and quick way to apply a
differential signal created from a single-ended source
(e.g., HP/AGILENT 8644B signal generator) and a wide-
band transformer. Alternatively, these inputs can be
driven from a CMOS-compatible clock source; however, it
is recommended to use sinewave or AC-coupled differ-
ential ECL/PECL drive for best dynamic performance.
