LE79489-3DJCT Application Field and Working Principle

LE79489-3DJCT, a field programmable Gate Arrays (FPGA) integrated circuit by STMicroelectronics, can be employed in a wide variety of architectures and Protocols, mainly featuring telecom applications. Technically known as a Programmable logic device (PLD), this kind of technology was designed to be used in combination with networks like GSM, 3G, 4G and 5G in order to add switching flexibility, aiding in the development of newer, more reliable, and more low-cost solutions.

This device offers RF coverage up to 8 GHz, reducing the need for external filter components. It is nowadays widely used in products such as GSM dual-band handsets and radio-frequency power amplifiers. This technology implements a 5-bit I/O addressing scheme which considerably reduces PCB area and cost.

Working Principles

The logic in FPGA is mainly arranged in two basic structures: a matrix of flip-flops and a matrix of programmable interconnects.The Flip-flops define registers or delay elements, while the interconnects are to provide access to the logic blocks available within the logic structure.

LE79489-3 DJCT utilizes those basic concepts, providing on the same chip an array of logic blocks composed by four inputs and one output. Additionally, a fast embeded multiplier and square root accelerator (MSRA) is implemented, speeding up 4G and 5G modem applications. There\'s also the possibility to perform Structural Test Access Port (STAP) operations through the powerful Number of Clocks (NoC) micro-architecture.

The LE79489 employs a combination of advanced interconnection routing, power management circuits and clock management strategies to minimize the overall power consumption, while providing an impressive data rate throughput. Moreover, a pair of built-in Digital Radio Frequency Interference (DRFI) Circuit filters is intended for application specific noise reduction, making it an excellent choice for radio-transceiver applications.
