MB86060 16-bit Interpolating Digital to Analog Converter
If a common, system wide logic level clock source is to be used, this should be transformer coupled
to remove common mode noise and isolate the clock ground region. The recommended 1:1
impedance transformer is a Mini-Circuits, ADT1-1. The secondary will be connected to the differential
clock inputs CLK and CLKB, and terminated with a 100
should be 50
source and the digital clock source ground. A 100 source resistor is used, and the PCB tracks to
the clock source should be 100 . See figure 16c.
For connection to a low noise RF source, a Balun transformer should be used. The recommended
transformer is a Mini-Circuits ADTL1-4-75. The secondary terminals should be connected through a
100nF capacitor to the differential clock inputs CLK and CLKB. The clock inputs should be terminated
with a 50 resistor. The primary dot should be connected to the RF signal with a 50 PCB track, and
the other primary connection should be connected to RF ground. The primary ground may be
connected to clock ground if necessary. See figure 16d. This configuration would allow for a RF
signal level of between -6dBm and +24dBm, giving a differential signal level of up to 5V pk-pk at CLK
and CLKB.
