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 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 6GHz.
See Figure 1 and Application Note for RF Prescalers for
more details.
