ntroduction

Our hardware expertise can provide you with a full range of

services including functional specifications and requirement

documentation, schematics, layout, prototype manufacturingand testing. At the low end, we have designed embedded

control systems that employ 8 bit micro-controllers and

system interface control logic either in discrete logic orCPLD's / FPGAs.

We are the third party developers for Freescale

Semiconductors

At higher end, the designs have included 8/16/32 bit

microprocessors from almost all the major vendors; StaticRam, Flash memory, communication interface devices,

display controllers. Many designs also incorporate multiple

controllers with necessary handshaking & using commonresources such as memories etc. Some products are designed

using DSP's from TI & Analog Devices for high speed

analog signal processing, Math applications & algorithms.

The control logic for each design has been implemented

utilizing an appropriate technology, such as PAL's, CPLDsor FPGA's. We can offer Altera, Actel, Xilinx and Quick-

Logic FPGA based designs, including converting discretelogic circuits into FPGAs.

Our design expertise span around mixed signals using

extensive analog circuits to process high frequency, low

level signals & interfacing the same using ADC's up to 16 bits resolutions. The power supplies required for these

designs are also designed in-house. Designs are

implemented using multiplayer boards & using SMT &

designed to meet various EMI/EMC requirements for highspeed mixed signal circuits.

PCB Design Expertise

EmSyS offers a wide range of PCB Design services,

including Centralized Component Library creation,Schematic creation, PCB routing, Gerber reviews and

Prototype development. Most of our engineers are IPCcertified and have extensive experience in PCB designservices.

Our Product Development Cycle ensures that the Electrical

engineering team and PCB team work together to ensure that

the components are placed to meet the mechanicalconstraints and the PCBs are routed to meet the required

safety and EMI / EMC Standards.

EmSyS has close relations with many of the PCB vendors

who deliver high quality boards within our required time.EmSyS also has close relationship with the contract

manufacturing facilities in India who can assemble our

boards and deliver it to us as per our requirement.

EmSyS has license for almost all the major tools that arebeing used in the current PCB design industry. Some of

them have been listed below.
