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.
