Description
The ZL40804 are Bipolar 3.45V supply, very low power
prescalers for professional applications with a fixed
modulus of 4. The ultra low close in (10KHz 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.
