Layout Considerations
To achieve stable, low noise performance good analog layout techniques should be incorporated and a
partial list includes:
The CD-700 should be treated more like an analog device and the power supply must be well decoupled
with a good quality RF 0.01 uf capacitor in parrallel with a 0.1 uF capacitor, located as close to pin 14 as
possible and connected to ground. In some cases, a pi filter such as a large capacitor (10uF) to ground, a
series ferrite bead or inductor, and 0.01 uf and 100 pf capacitor to ground to decouple the device supply.
The traces for the OUT1, OUT2, RCLK and RDATA ouputs should be kept as short as possible. It is
common practice to use a series resistor – 50 to 100 ohms – in order to reduce reflections if these traces
are more than a couple of inches long. Also OUT1, OUT2, RCLK and RDATA should not be routed
directly underneath the device.
The op-amp loop filter components should be kept as close to the device as possible and the feedback
capacitor should be located close the op-amp input terminal. The loop filter capacitor(s) should be low
leakage and polarized capacitors are allowed keeping this is mind.
Unused outputs should be left floating and it is not required to load or terminate them (such as an PECL or
ECL output). Loading unused outputs will only increase current consumption.
