Digital Controller

ZMDI, Dresden, Germany, released the ZSPM2000 configurable digital PWM controller with integrated MOSFET driver for smart digital point-of-load (POL) solutions. The controller operates as a synchronous step-down converter in a single-rail, single-phase configuration. It features an integrated power-stage driver, and digital communication and control via the PMBus™ interface. Other features include digital-control algorithms, anti-cross-conduction, and power-saving features.

Serial Communication Cards

ACCES I/O Products, San Diego, CA, announced mPCIe-ICM Series PCI Express Mini Card isolated serial communication cards that measure 30 × 51 mm and feature a selection of four or two ports of isolated RS-232 serial communications. Features include 1.5kV isolation provided port-to-computer and 500V isolation port-to-port on all signals at the I/O connectors. The cards provide ±15kV ESD protection on all signal pins, and use 128-byte transmit/receive FIFO buffers to decrease CPU loading and protect against lost data in multitasking systems.

Circuit Design Tool

Sunstone Circuits, Mulino, OR, announced DFMplus, a Design to Manufacturing tool that allows potential issues to be fixed in the PCB design phase. The tool helps users verify PCB designs before ordering. The tool features a preview of possible failure points, provides efficient transfer of design file data into manufacturing, and enables designers to submit partial designs, or regions of the design, as a section-by-section check.

Data Acquisition Board

Measurement Computing (Norton, MA) offers the USB-2020 high-speed, two-channel data acquisition board that provides simultaneous sampling at rates up to 20 MS/s per channel. Users can sample data from both channels at an overall rate of 40 MS/s to the 64-megasample onboard memory, or continuously stream data to a host computer at up to 8 MS/s for one or both channels over a high-speed USB connection. Each channel has its own A/D converter for simultaneous sampling to eliminate channel skew and ensure that phase information between channels is maintained.

Oscilloscope

The LabMaster 10-100Zi 100-GHz oscilloscope from Teledyne LeCroy (Chestnut Ridge, NY) achieves 100 GHz and 240 GS/s. The 100-GHz technology is designed for engineers working on communication systems, high-bandwidth electrical components, and scientific research. The modular and flexible platform allows users to build oscilloscopes with high channel counts, even when only one or two channels are in the base model. The oscilloscopes are built from a single Master Control Module (MCM-Zi) that contains the display, control, and ChannelSync clock distribution architecture, managed by a server-class CPU.
