The cost-effective solution is able to rapidly locate and lock-on to weak GPS signals to provide precision time even when only 1 satellite is visible. The u‑blox solution was selected based on its “SuperSense” and proprietary noise-suppression technology allowing base stations to be placed in locations where satellite signals are very weak such as dense urban areas and inside buildings.
We are proud that u‑blox' precision timing solution was chosen to support these exciting new services in China," said Adrian Tan General Manager Asia, u‑blox.
"Wireless third-generation networks require strict synchronization of data streams to ensure reliable signal handoff between base stations, and to facilitate accurate accounting for 3G services such as streaming video, MMS, and high-speed Internet. The 3G standard was recently adopted by China Mobile, the world’s largest mobile service provider.

The u‑blox solution is used in base stations for China’s newly established TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) 3G standard, which is currently being rolled-out across the People’s Republic of China.

The RC32614A ClockMatrix 2 system synchronizer is available now. Optional PTP Clock Manager software is also available free of charge under license for use with the RC32614.The solution, based on the u‑blox LEA-4T and LEA-5T GPS modules, allows cellular base stations to achieve precision time-of-day to an accuracy of 15 billionths of a second. Renesas offers more than 250 Winning Combinations with compatible devices for a wide range of applications and end products. The ClockMatrix 2 system synchronizer can be combined with Renesas’ complementary analog and power offerings to create comprehensive solutions for a variety of applications. For example, ClockMatrix 2 is integrated into the 200/400/800Gbps Fixed Form Factor Switch Solution Winning Combination, along with analog and power offerings from Renesas.

Key Features of the ClockMatrix 2 Family include: Highly integrated, 6-channel precision timing source that eliminates the need for additional jitter attenuators for high-speed interfaces 88fs-rms phase jitter on clock outputs to support ultra-low jitter clock outputs for high-speed serial links (up to 112Gbps PAM-4 PHYs) Supports multiple standards and protocols including synchronous Ethernet (Sync-E), and IEEE1588 Adherence to G.8262.1 and G.8262 telecom boundary clock requirements and G.8273.2 Class C and Class D time accuracy
The highly integrated devices provide all the functionality needed to implement an IEEE1588 clock solution with jitter attenuation capabilities resulting in ultra-low jitter clock outputs for Synchronous Ethernet PHYs with data rates up to 112Gbps PAM-4, reducing design complexity and bill of materials (BOM) requirements, while also allowing customers to apply the timing devices to a wide variety of network applications. Renesas Electronics Corporation introduced the ClockMatrix 2 high-performance, precision, multi-channel timing devices for 400/800Gbps optical transport and wireline network applications. Building on the ClockMatrix devices introduced in 2019 for 5G wireless and 100/200Gbps wireline network applications, the second-generation family delivers improved performance with phase jitter as low as 88fs-rms.
