The MLX90121 is an ISO compliant 13.56MHz RFID transceiver integrated circuit.
The main features include user selectable modulation depth in write mode, whereas single sub-carrier ASK, FSK and PSK modulations are recognized in the read mode.
The receiver is based on a diode envelope detector, followed by an IF filter and amplifier. A logarithmic amplifier is used for single subcarrier ASK detection, ensuring fast and clean data recovery. The limiting output of the log amp is used for FSK and PSK recovery.
The transmitter uses a built in open drain output transistor, which can provide up to 250 miliwatts of RF power to a 50 ohms load with a 5 volts power supply using the recommended matching network. This is suitable for most short to mid range applications. A simplified antenna and matching network can be used, at the expense of a reduced reading range, for example in hand-held reader applications.
The chip is configured with a serial interface. A synchronization signal is available when the majority voting is used.
Digital part contains ASK, FSK (423 / 484kHz)and PSK (847kHz) decoders and a programmable encoder to facilitate data handling with a low cost microcontroller. The encoder can be programmed with 6 different patterns.
The chip can also be used as an analog frontend, in direct mode.

SDRAM was developed immediately after EDO generation products. It is a breakthrough in that it synchronizes the frequency to the system clock that controls CPU. Synchronization of CPU and frequency minimizes time delays and facilitates memory retrieving process.
SDRAM has been used for PC, server and network, and now its usage is expanding to various consumer electronics such as printer, DSC, HDD and STB.

Multi-function smart cards replace traditional tokens, Photo ID badges, and proximity cards, while providing a variety of new functions for a greater return on investment.
Smart cards provide the most secure platform for the convergence of building and facility access. Business and government organizations around the world are using smart cards to reduce security risk exposure, to comply with regulations such as HIPAA, PIV, Sarbanes-Oxley and Basel II, and to reduce the administrative costs of existing forms of identification.

XDR DRAM(eXtreme Data Rate DRAM ) is based on XDR memory interface technology developed by Rambus and offers several innovative techniques that include ODR(Octal Data Rate), DRSL(Differential Rambus Signaling Level) and etc.
As a result, XDR DRAM achieves an order of magnitude higher performance than today's standard memories.
XDR DRAM has three speed grades, ranging from 2.4GHz to 4.0GHz, with the expectation that data transfer speeds will rise to 8.0GHz in the near future.
XDR DRAM is best memory solution for wide-ranging applications including video console games, digital televisions, computer servers, workstations and other applications where high bandwidth and low latency are required.
