Description
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.
See Figure 1 and Application Note for RF Prescalers
for more details.
