The dividing elements are dynamic D type flip flops and allow operation from 10.5GHz to 13.5GHz with a sinewave input (Note these prescalers are not suitable for D.C. operation). The output stage has internal 50 ohm pull up giving a 1v p-p output. See application notes for more details.

The above circuit diagram shows some components in dotted lines. These are optional in many applications. 1. C1 (10 F) and C2 (10 nF) power supply decoupling capacitors may be available on the board already. 2. R2 (100 Ohm) and C8 (10 nF) can be included if further power supply decoupling is required for the first stage biasing circuit. This may optimise the noise and jitter performance. The values are suggestions and may have to be modified if the existing supplies are particularly noisy. 3. R1 (50 Ohm), in series with C5 (100 pF), may reduce feedthrough of the input signal to the output. 2 Zarlink Semiconductor Inc. Data Sheet 2.0 Evaluation Boards From Zarlink Semiconductor ZL40813/14/18 Zarlink Semiconductor provide a prescaler evaluation board. These are primarily for those interested in performing their own assessment of the operation of the prescalers. The boards are supplied unpopulated and may be assembled for single ended or differential input and output operation. Once assembled, all that is required is an RF source and a DC supply for operation. The inputs and outputs are connected via side launch SMA connectors.

This represents the circuit used to complete characterisation. The tabulated Electrical performance is guaranteed using this application circuit. A blank application board is available. 5.1.1 Circuit Options The application circuit includes some optional components that may be required to improve tolerance of system noise present in the application. Dummy R source may be added to the inverting input to provide a better matched source impedance at the input. This will improve the rejection of common mode noise present within the system. Dummy R load may be added to the inverting output to provide better matched load at the output. This will reduce the radiated EMI at the output and reduce the Output Noise present on the supply rail. Rfilter can be inserted between the Vcc in and the Vcc_out to provide additional filtering to the input Vcc. The input Vcc powers the input bias reference only and can be a sensitive point to system noise. The nominal input current at Vcc_IN s 0.35mA. An alternative would be to use an inductive choke. C1 is additional Supply Filtering and should be added with Rfilter. The IC includes 10pF of on Chip Supply Filtering. 12 Zarlink Semiconductor Inc. Data Sheet 5.2 Single Ended or Differential Load ZL40813/14/18 Figure 16 and Figure 17 illustrate the output waveform when measured differential and single ended with a 10GHz waveform at the input at a level of +2dBm. The single ended output contains some input frequency break through which contributes to the distortion present. This is a common mode signal which is rejected if the output is taken differentially. Differential operation also provides an additional 3dBV output power. Differential Operation reduces the radiated EMI in the system and reduces the susceptibility to common mode system noise. NOTE: It is strongly recommended that these devices are used differentially for all applications. Zarlink Semiconductor Inc. 13 ZL40813/14/18 Data Sheet 14 Zarlink Semiconductor Inc.
