| Low cost, Low Bit-Rate RALCWI Vocoder IC |
 |
| |
 |
|
CML announced the introduction of a new RALCWI (Robust Advanced Low Complexity Waveform Interpolation) vocoder IC. The CMX618 is a flexible, half-duplex, highly integrated RALCWI vocoder IC suited to both wireless and wireline voice applications such as voice scramblers, alarm systems, military field-applications and digital professional/leisure two-way radios (DMR/dPMR), to name but a few examples.

Fully integrated PoE PD interface and switching regulator
|
 |
| |
 |
|
The Si3400 and Si3401 are complete power supply solutions for Power over Ethernet (PoE) Powered Device (PD) applications. The Si3400 is the industry’s most highly integrated, IEEE 802.3af compliant, PoE PD interface and pulse width modulated (PWM) switching regulator. By setting a new bar for device integration, lowest overall BOM cost, efficiency and reliability, the Si3400 enables to easily add PoE functionality to Ethernet products.

The Multi-Tech SocketModem® embedded modem creates communication-ready devices by integrating data/fax modem functionality into a single, universal socket design. The SocketModem embedded modem utilizes a space efficient (1" x 2.5"), design that allows OEMs to integrate a wide range of modem functions and speeds into any product platform. The complete, ready-to-integrate modem dramatically reduces development time and costs for system designers. The SocketModem embedded modem complies with telecom requirements globally and can be shipped worldwide.

Quad and Dual Port Gigabit Discrete Isolation Transformer Modules 50 Percent smaller |
 |
| |
 |
|
These new Pulse gigabit modules are 50 percent smaller than currently available modules, so printed circuit board (PCB) designers can fit more components on the circuit board or further reduce the circuit board size for greater design flexibility. Taking advantage of the ball grid array (BGA) technology, these surface mount modules are solder bumped and tested for easy surface mount (SMT) attachment to the PCB for computer, telecommunications, and networking applications such as Power over Ethernet (PoE), small office home office (SOHO), hubs, routers, and switches. Pulse's Quattro H5400NL and H5401NL quad-port modules are 29mm long x 17.5mm wide x 11mm high, while the Dos H5200NL and H5201NL dual-port are 14.7mm long x 17.5mm wide x 11mm high. The quad-port fits perfectly behind a 2x2 RJ45 connector making board layout easier and more compact.

SocketModem® Development Boards

In some cases you may wish to implement different connectivity options to your application. This would in most cases require different board configurations to fit say an Ethernet solution or GSM/GPRS modem instead if a dial-up modem. Chipset design may involve purchasing multiple reference design or development boards which can be a costly and time consuming exercise and will increase your BOM or VPL when you move to productionise the design with multiple board build options. One way around this is to opt for a MultiTech SocketModem® based design, the basis of which is to have a single sytem design that allows OEMs to populate it with a wide range of connectivity technologies using industry standard AT command driven, communication-ready SocketModem® modules.This is where the benefits of using MultiTech's flexible com-port architecture will come into its own. The space efficient 2.7 x 6.5cm Universal Socket provides analogue dial-up, ISDN, GSM/GPRS, EDGE, Bluetooth or ethernet connectivity with interchangeable modules.
Available Development Boards:
- MTSMI-UDK – universal dev board for all serial socketmodems
- MTSMI-P-DK – universal board for all parallel modems
- MTIFM-DK – board for the MTIFM
- MTRJ-DK – board for the MT5656RJ
- MTMMC-DK – board for the MTMMC
