s148-fx4 site stand alone TIM carrier – Single input voltage version

There are two versions of the SMT148-FX available. The DC version, and the ATX version.
The DC version uses a DC input and DC-DC converters to attain the required voltages, where as the ATX version uses a PC type power supply.
The SMT148-FX-nn-Fxxx with an additional local ADC oscillator is also an option. “nn” refers to power input type (DC or ATX). “Fxxx” refers to the oscillator frequency.

The SMT148-FX is a brand new concept in the growing portfolio of Embedded Processing solution that Sundance offers and it’s a highly compact fully integrated, expandable with Sundance Processing and I/O Modules and will run from stand-alone variable DC power supply as all the voltage conversation are on-board.

The Virtex-4 FX60 on-board the SMT148-FX is only partly used, so User can get access to the spare gates by using the Diamond FPGA tools. The FX60 has also got two PowerPC hard-cores and these will be support by Diamond PowerPC in Q1 2008 and would enable a stand-alone solution with Embedded PowerPC, FPGA and DSP for the ultra demanding applications.

s148-fxbtmThe SMT148-FX sports a range of I/O interfaces, like 48MHz USB2.0, 1Giga Ethernet; SATA harddisk connections, RS232/RS422 and more than 40 LVDS signals that can be used for control or interface to flat-screen displays. The addition of a FireWire interface, combined with the use of Serial Links for extra communication makes it possible to cascade and synchronize SMT148-FX to suit any requirements.

The SMT148-FX enables a truly portable system to be developed and run as a “Self-contained” unit, and if used, the on board up to 1Gb/s Ethernet interface provides a Internet compatible system. Being able to use a range of input voltages the SMT148-FX can be used anywhere from the desktop, in an embedded system, a car or even a push bike. The four module sites enable a large scope for a variety of DSP, FPGA, DAC and ADC applications and computations.
