Clock and Timing

Clock and Timing – Applications

TI's solutions include a wide range of products – clock buffers, clock generators, clock jitter cleaners, and RF PLLs and synthesizers – for a broad range of applications including wired and optical communications, wireless communications, industrial, and automotive.

Wired Communications/Networking

Low-jitter clocks enhance system performance by ensuring excellent signal integrity at high data rates

With increasing data rates in networking and wired communication applications, clock jitter has become a major bottleneck for maintaining signal integrity. TI's ultra-low jitter clock jitter cleaners and clock generators improve system performance while reducing the bill-of-materials (BOM) by consolidating several oscillators. Equipped with a flexible architecture and advanced features such as holdover, TI's clock and timing ICs increase system performance, flexibility, and robustness.

Wireless Communications

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.
