Description
Description The ZL40812 is one of a range of 5V
supply, very high speed low power prescalers for
professional applications with a fixed modulus of divide
by 16. The dividing elements are static D type flip flops
and therefore allow operation down to DC if the drive
signal is a pulse waveform with fast risetimes. The
output stage has internal 50 ohm pull up giving a 1V p-
p output. See application notes for more details.

Example Configuration for Single ended operation
Figure 2 - 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. R3 (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.
4. R2 (50 Ohm) and C7 (10 nF) will help to balance the current drawn from the power supply and may reduce volt-
age transients on the power supply line
