Timing product for advanced enterprise-class systems in networking and communications

Integrated Device Technology have introduced a uniquely flexible frequency synthesizer that hands the system designer options to pre-configure the settings of the device or program them in the system, or a combination of both. With an industry-first eight fractional and two integer output dividers, the IDT 8T49N1012 FemtoClock NG synthesizer delivers a single-chip solution that aids design engineers in resolving complex timing requirements while hitting important performance parameters. The new timing product is ideal for advanced enterprise-class systems in networking and communications, as well as printing, computing, instrumentation, audio, video, backplane and USB applications. The flexibility and cost effectiveness of the device alone makes it ideal for virtually any general timing requirement. “Clock trees generate and control the signals sent throughout today’s advanced electronic systems, and it is essential that these timing devices deliver highly synchronized top-tier performance,” said Kris Rausch, general manager of IDT’s Multi-Market Timing Division. “With the flexibility built into the 8T49N1012, our customers can use a single device to generate essentially any clock needed for most applications, minimizing board space occupation, BOM and component count. The in-system configurability of this 12-output clock generator allows it to be portable from one design to the next, further reducing cost of ownership and time to market.” The device is programmable through an I2C interface and also supports master capability, allowing the register configuration to be read from an external EEPROM. This capability is beneficial in providing a means for system quick recovery upon resolution of a general system fault. In addition, programmable skew control on all eight fractional outputs allows for easy in-circuit trace delay adjustments. IDT’s Timing Commander software tool enables fast and easy reconfiguration of the device, which aids engineers when dealing with overall design iterations.
