Description
The ZL40813, 14 and 18 are 5V supply, very high speed low power prescalers for professional applications with a fixed modulus of 8, 16, or 4 respectively. 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.

Application Configuration
Figure 3 shows a recommended application configuration. This example shows the devices set up for single-ended input and differential output operation.

F i g ur e 3 - Recommended circuit configuration. The above circuit diagram shows some components in dotted lines. These are optional in many applications. 1. C1 (10 µF) 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. 0 Evaluation Boards From Zarlink Semiconductor
Data Sheet
Zarlink Semiconductor provides prescaler evaluation boards. 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, type No. ZLE40008. Fully populated evaluation boards are also available, type No. ZLE40810. 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.

These characteristics are guaranteed by either production test or design. Pin 1 is the Vcc pin for the 1st stage bias current. In some applications e.g. if the power supply is noisy, it may be advantageous to add further supply decoupling to this pin (i.e. an additional R, C filter, see diagram of the recommended circuit configuration Figure 3,).
