productroundup 10-year MCU availability 4-6 GHz down converting mixer  NXP Semiconductors has introduced a Product Longevity Program for its ARM Cortex-M microcontrollers with a minimum available period of 10 years, guaranteeing continuity and stability of supply for those that design industrial control applications and require long-term product availability. The first microcontrollers in this Program are from NXP’s Cortex-M0 family: LPC1100XL, NXP’s lowest-current MCU with 110µA/MHz performance; LPC1100L in low-pincount SO, TSSOP and DIP packages; LPC11U00, a USB Cortex-M0 with integrated ROM drivers; LPC11C00 with on-chip CAN transceiver; and LPC11E00 with integrated 4 kB EEPROM.  LTC5544 is a 4 GHz to 6 GHz high dynamic range downconverting mixer that offers high linearity with 25.9 dBm IIP3 (Input Third-Order Intercept), high conversion gain of 7.4 dB owing to its integrated IF amplifier, and a noise figure of 11.3 dB. Use it to optimise dynamic range performance for both main receivers and digital pre- NXP Semiconductors, www.nxp.com/products/ microcontrollers/#description distortion receivers. The chip’s RF input can tolerate strong interference signals without significantly degrading its noise figure, preserving receiver sensitivity. It incorporates an on-chip integrated high gain IF amplifier capable of supporting IF frequencies up to 1 GHz. Also integrated are an LO buffer along with two RF balun transformers. They enable the RF and LO inputs to operate singleended and with 50Ω matching. The LO input requires only +2dBm drive level. LTC5544 operates on a single 3.3V supply, drawing 194mA of current, with a power-down feature with 0.6 µsec turnon and turn-off time, supporting Burst Mode operation or TDD (time division duplexed) systems. When disabled, the device consumes a maximum of 500µA. It costs $8.50 (1000). Linear Technology, www.linear.com/product/LTC5544 Beyond-the-rails switches  MAX14778 (analogue mux) and MAX14759– MAX14764 (analogue switches) handle signal level of ±25V above- and below-the-rails so that you can switch or multiplex a wide signal range from standard 3V to 5.5V supplies: you no longer need multiple switches/muxes to switch both high- and low-voltage signals. The ±25V MAX14778 mux can multiplex up to eight channels, in applications requiring connector sharing such as multiplexing RS-232, USB, RS-485, CAN, or audio. The ±25V signal capability of all the devices enables switching of true RS-232 signals for connector sharing applications. For analogue input applica- tions, the wide voltage range provides a robust signal range to accommodate harsh industrial environments. With a 75 MHz (min) bandwidth, they also switch Full Speed USB (12 Mbps). The low 1.5Ω (Max) RON and 3 mΩ (typ) RON flatness of the MAX14778 ensure precise voltage measurements over temperature. The MAX14778 mux is packaged in a 20-pin TQFN. The MAX14759/MAX14760/MAX14763/ MAX14764 switches are available in an 8-pin TDFN, and the MAX14761/MAX14762 in a 10-pin TDFN. All devices are specified over the -40°C to +85°C temperature range. Pricing starts at $1.88 (1000). Maxim , www.maxim-ic.com/datasheet/index.mvp/id/7406 www.maxim-ic.com/datasheet/index.mvp/id/7503  CompactPCI interposer for PCIx 2.0 analysis GT/sec, supporting debug of problems such as inconsistent board initialisation, poor I/O performance, and power up issues. You can, LeCroy says, more easily identify protocol errors and performance issues that otherwise slow down development and testing of new or updated products with intuitive software views and built-in protocol translations. LeCroy has developed a PCI Express 2.0 CompactPCI Serial interposer for the Summit PCI Express Protocol Analyser. The interposer provides a dedicated probe that makes it easier to analyse in-band PCI Express data traffic between a CompactPCI Serial card and its system chassis. It supports PCIx data channels with lane widths up to x8 at data rates up to 5  LeCroy , http://cdn.lecroy.com/files/pdf/lecroy_ compactpci_serial_interposer.pdf 60 EDN EUROPE | MAY 2012 www.edn-europe.com http://www.nxp.com/products/microcontrollers/#description http://www.linear.com/product/LTC5544 http://www.maxim-ic.com/datasheet/index.mvp/id/7406 http://www.maxim-ic.com/datasheet/index.mvp/id/7503 http://cdn.lecroy.com/files/pdf/lecroy_compactpci_serial_interposer.pdf http://www.edn-europe.com
