NLAST4501DFT2G

Introduction

The NLAST4501DFT2G is an Interface - Analog Switches, Multiplexers, Demultiplexers for wireless, communications and datacom nodes. It combines four channels of low power monolithic analog switches, multiplexers, and demultiplexers with a logic level control circuit. This device works with dual supplies: a logic level supply ranging from 2.3V to 3.6V, and also an acoustic signal voltage supply ranging from <1V to 3V. This device is designed to be easily integrated into wireless, communication and data-com nodes.

Applications

The NLAST4501DFT2G is typically used in wireless and communication nodes such as wireless base bands, GSM/CDMA, Wi-Fi and other short-range communication system. It can be used to switch the timing control signals, the transmit and receive data channels, and more. It also can be used to switch the digital control signals like switching the clock source for clocking the devices. Furthermore, it is frequently used as a digital-to-analog converter as it can convert the low level logic signals from the digital domain to an acoustic signal in the analog domain.

Working Principle

The working principle of the NLAST4501DFT2G is based on using the dual voltage supply. The logic level voltage (Vdd) is applied to one side of the device and the acoustic signal voltage (Vcc) is applied to the reverse side of the device. A logic level oscillator signals a clock input which then switches between channels in order to access the required channel. The logic signals are converted to low level logic by the logic level circuitry and then switches as required between channels. The acoustic signal is then converted back to a logic signal and outputted according to the chosen channel.

Conclusion

The NLAST4501DFT2G is a versatile analogue switch, multiplexer, and demultiplexer that is suitable for a wide range of wireless, communication and data-com applications. The dual voltage supply allows for a versatile range of voltage levels for efficient digital-to-analog conversion, and the logic level oscillator enables switching between channels. The ability to switch between channels is convenient for anyone attempting to switch from one type of signal to another. The NLAST4501DFT2G is an excellent choice for anyone attempting to convert a low level logic signal from the digital domain to an acoustic signal in the analog domain.
