Synthesiser delivers unparallelled frequency flexibility
Enabling system designers to pre-configure the settings of the device, programme them in the system or a combination of both, Integrated Device Technology has introduced a uniquely flexible frequency synthesiser. The 8T49N1012 FemtoClock NG synthesiser delivers a single-chip solution that aids design engineers in resolving complex timing requirements while hitting important performance parameters.
With a claimed industry-first eight fractional and two integer output dividers, this timing product is suited 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 suitable for virtually any general timing requirement.
Kris Rausch, General Manager, Multi-Market Timing Division, IDT, commented: “Clock trees generate and control the signals sent throughout today’s advanced electronic systems and it is essential that these timing devices deliver highly synchronised top-tier performance. With the flexibility built into the 8T49N1012, our customers can use a single device to generate essentially any clock needed for most applications, minimising 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 8T49N1012 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.
The 8T49N1012 FemtoClock NG synthesiser is available in a 10x10mm 72-VFQFN package, priced at $4.60 each in 10,000 unit quantities.
