Description
The ZL40800 and ZL40802 are Bipolar 3.45V supply,
very low power prescalers for professional applications
with a fixed modulus of 8 or 16. The ultra low close in
(1KHz offset) SSB phase noise performanc e 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 6GHz.
See Figure 1 and Application Not e for RF Prescalers for
more details.
