MÜNCHEN — Zweistelliges Umsatzwachstum und steigende Beschäftigung erwartet der Branchenverband Spectaris für optische Komponenten der Nachrichtentechnik. Der Grund: Die anhaltende Digitalisierung lässt den Bandbreitenbedarf in den Datennetzen drastisch ansteigen.

The addition of AMD's OpenGL ES 2.0 and OpenVG 1.0 graphics technologies to Freescale's family of i.MX applications processors will help us deliver an even broader portfolio of platform solutions to manufacturers worldwide,” said Paul Marino, general manager of Freescale's multimedia division, speaking in a prepared statement.

The adoption of AMD graphics technology by a world-leading semiconductor supplier validates our belief that graphics and attractive user interfaces are driving growth and revenues throughout the wireless industry,” said Adrian Hartog, senior vice president and general manager of AMD's consumer electronics group in the statement.

Rohde & Schwarz presents the R&S FSG, a spectrum analyzer for cost-conscious users that is tailored to meet current requirements in the development and production of wireless communication products. The R&S FSG supports all the standards of the 2nd and 3rd mobile radio generation as well as current broadband technologies such as WiMAX. Featuring a demodulation bandwidth of 28 MHz, the spectrum analyzer can already handle the measurement tasks of the UMTS LTE mobile radio generation. Its high dynamic range, a frequency range up to 13.6 GHz, and the integrated vector signal analysis make the R&S FSG a powerful tool for the general analysis of digitally modulated signals.

The R&S FSG spectrum analyzer is ideal for a wide range of applications, e.g. in development labs, production lines, and as a reference for product verifications. Measurement applications for internationally common standards such as GSM, WCDMA, CDMA2000® 1xRTT, TD-SCDMA, HSPA, Bluetooth®, WLAN or WiMAX are available, if required, at the press of a button. Owing to its I/Q demodulation bandwidth of 28 MHz, a high dynamic range of, for example, 170 dB between 1 dB compression point and DANL, as well as integrated vector signal analysis, the scope of functions of the R&S FSG is ideal for modern development labs. The customized operating concept of the Rohde & Schwarz spectrum and signal analyzers also supports the user in the development of new mobile radio products.

In addition, the R&S FSG provides maximum throughput in production lines. It features a high measurement speed of, for example, 2.5 WCDMA code domain measurements per second. The spectrum analyzer is also precise and reliable: With 3G, it has an inherent EVM of below 0.7 percent while offering best repeatability of the results. The R&S FSG is equipped with the same remote-control command set asall spectrum analyzers from Rohde & Schwarz. Users who already have instruments from Rohde & Schwarz will thus be able to integrate thenew spectrum analyzer into their test environments without additional programming effort and keep operating costs low.

The R&S FSG is available in the frequency ranges up to 8 GHz and 13.6 GHz. The spectrum analyzer provides GPIB, LAN (10/100BaseT), and USB 2.0 interfaces and is also compatible with the LXI Class C. For highly accurate determination of absolute signal powers, the R&S NRP power sensors can also be directly connected to the instrument.

The R&S FSG spectrum analyzer is now available from Rohde & Schwarz.

Frequency scaling Frequency scaling is a technique in which an IP block is operated at one of two (or more) clock frequencies. The clock frequency is changed in response to system activity and workload requirements on this IP. Lowering the clock frequency to a CS-IP reduces its dynamic power. The impact on the internals of the CS-IP can be minimized by careful analysis and checks as indicated in Table 1.

Because the frequency of the clocks to the CS-IP can't be changed on the fly, there needs to be a suitable on-chip control unit to sequence the transition. A separate sequence is required to transition the clocks from a high to low frequency and visa-versa. A typical sequence for the transition is shown in Table 2.

These steps are followed in the same order while transitioning back from a lower frequency to the normal operating frequency. The actual sequencing of clocks however, might differ. While transitioning the clocks, the CS-IP is temporarily disabled and it's imperative to minimize this period.
