Wireless Communication

Low-noise clocks and synthesizers maximize data converter and overall signal chain performance

Clock jitter and local oscillator (LO) phase noise are key elements in the radio signal path and can directly impact the quality of the RF signal being received and transmitted. Likewise, in the baseband boards, clocks can impact the signal integrity of the high-speed link to and from radio. With industry-leading performance, TI's clock jitter cleaners, clock generators, clock buffers, and RF PLLs and synthesizers maximize the quality and robustness of wireless links.
