IDT’s family of high-performance, low additive phase noise buffers is the ideal choice for use in designs where a clean frequency source is critical to a system’s operation and performance. IDT fan-out buffers feature fully differential internal architecture, reducing jitter caused by inherent common-mode noise rejection and improving output skew. The differential circuitry is constant-current and therefore injects less noise into system power supplies than single-ended solutions, reducing EMI compliance concerns. These buffers are typically used for clock distribution on wireless infrastructure designs of radio boards where low phase noise is required. IDT’s buffers are ideal for space-constraint designs by offering small footprint packaging as well as integrating the input termination network for differential signals.
