9 / 14 page CD-700, VCXO Based PLL Vectron International, 267 Lowell Rd, Hudson NH 03051-4916 Tel: 1-88-VECTRON-1 • Web: www.vectron.com Page 9 of 14 Rev : 06Apr08 Layout Considerations To achieve stable, low noise performance good analog layout techniques should be incorporated and a partial list is shown below. 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 parallel with a 0.1 uF capacitor, located as close to pin 14 as possible and connected to ground. In some cases, a Π filter such as a large capacitor (10uF) to ground, a series ferrite bead or inductor with 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 to the op-amp input terminal. The loop filter capacitor(s) should be low leakage (polarized capacitors are allowed). Unused outputs should be left floating and it is not required to load or terminate them (such as an ECL or PECL output). Loading unused outputs will only increase current consumption.
