Description
The ZL40815 is one of a range of 5 V supply, very high
speed, low power prescalers for professional
applications with a fixed modulus of divide by 4. 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 1 V p-p
output. See application notes for more details

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 optimize 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.
