Pin Configuration (Top View) When handling this UltraCMOS™ device, observe the same precautions that you would use with other ESD-sensitive devices. Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the rating specified in Table 6. pin 1 GND 2 IN 3 511 1 .

Pin Descriptions Device Functional Considerations Pin No. Pin Name 1 N/C No Connect. This pin should be left open. 2 GND Ground pin. Ground pattern on the board should be as wide as possible to reduce ground impedance. 3 IN Input signal pin. DC blocking capacitor required (100 pF typical). 4 VDD Power supply pin. Bypassing is required. 5 GND Ground pin. 6 OUT Divided frequency output pin. DC blocking capacitor required (100 pF typical). Description The PE3511 divides an input signal, up to a frequency of 1500 MHz, by a factor of two thereby producing an output frequency at half the input frequency. To work properly with low impedance, ground referenced interfaces, the input and output signals (pins 3 & 6) must be AC coupled via an external capacitor, as shown in the test circuit in Figure 4. The ground pattern on the board should be made as wide as possible to minimize ground impedance. See Figure 9 for a layout example. Table 6.

Page 5 of 8 PE3511 Product Specification Evaluation Kit bottom ground areas for best performance. Evaluation Kit Operation J6 provides DC power to the device via pin 4. Two decoupling capacitors (100 pF, 1000 pF) are included on this trace. It is the customer’s responsibility to determine proper supply decoupling for their design application. The SC-70 Prescaler Evaluation Board was designed to help customers evaluate the PE3511 divide-by-2 prescaler. On this board, the device input (pin 3) is connected to connector J1 through a 50 Ω transmission line. A series capacitor (C1) provides the necessary DC block for the device input. A value of 100 pF was used for this board layout; other applications may require a different value. The device output (pin 6) is connected to J3 through a 50 Ω transmission line. A series capacitor (C5) provides the necessary DC block for the device output. This capacitor value must be chosen to have a low impedance at the desired output frequency of the device. A value of 100 pF was chosen for the evaluation board. At both input and output, select a capacitor value that offers low series reactance while ensuring that any parasitic resonances are well above the operating bandwidth. The board is constructed of a two-layer FR4 material with a total thickness of 0.031”. The bottom layer provides ground for the RF transmission lines. The transmission lines were designed using a coplanar waveguide above ground plane model with trace width of 0.030”, trace gaps of 0.007”, dielectric thickness of 0.028”, metal thickness of 0.0014”, and εr of 4.4. Note that the predominate mode of these transmission lines is coplanar waveguide.
