Description
•
ZL40804 – Divide by 4
The ZL40804 are Bipolar 3.45 V supply, very low
power prescalers for professional applications with a
fixed modulus of 4. The ultra low close in (10 KHz
offset) SSB phase noise performance is ideal for
narrow band communications systems or systems with
ultra low jitter budgets such as next generation fibre
optic communications. The devices are broadband
from DC to 6 GHz.

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 is 0.35 mA. 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.

Single Ended or Differential Load
Figures 11 and 12 illustrate the output waveform when measured differential and single ended with a 5 GHz
waveform at the input at a level of +2 dBm. 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 6 dB output power.
Differential Operation reduces the radiated EMI in the system and reduces the susceptibility to common mode
system noise.
