DP83848CVVX/NOPB Original Electronic Component IC Chip Integrated Circuit

short description:

The PHY chip is an analog-digital hybrid circuit, which is responsible for receiving analog signals such as electricity and light. After demodulation and A/D conversion, the signal is sent to the MAC chip for processing through the MII interface. Generally, MAC chips are pure digital circuits. The physical layer defines the electrical and optical signals, line status, clock reference, data encoding and circuits required for data transmission and reception, and provides standard interfaces to data link layer devices. The physical layer chip is called PHY.

Description

The number of applications requiring Ethernet connectivity continues to increase, driving Ethernet enabled devices into harsher environments. The DP83848C/I/VYB/YB was designed to meet the challenge of these new applications with an extended temperature performance that goes beyond the typical Industrial temperature range. The DP83848C/I/VYB/YB is a highly reliable, feature rich, robust device which meets IEEE 802.3 standards over multiple temperature ranges from commercial to extreme temperatures. This device is ideally suited for harsh environments such as wireless remote base stations, automotive/transportation, and industrial control applications. It offers enhanced ESD protection and the choice of an MII or RMII interface for maximum flexibility in MPU selection; all in a 48 pin package. The DP83848VYB extends the leadership position of the PHYTER™ family of devices with a wide operating temperature range. The TI line of PHYTER transceivers builds on decades of Ethernet expertise to offer the high performance and flexibility that allows the end user an easy implementation tailored to meet these application needs.

The Classification Of The IC

Integrated circuits can be classified into analog or digital circuits. They can be divided into analog integrated circuits, digital integrated circuits and mixed-signal integrated circuits (analog and digital on one chip).

Digital integrated circuits can contain anything from thousands to millions of logic gates, triggers, multitaskers and other circuits in a few square millimeters. The small size of these circuits allows for higher speeds, lower power consumption and lower manufacturing costs compared to board-level integration. These digital ics, represented by microprocessors, digital signal processors (DSP) and microcontrollers, work using binary, processing 1 and 0 signals.

Analog integrated circuits, such as sensors, power control circuits and operational amplifiers, process analog signals. Complete amplification, filtering, demodulation, mixing and other functions. By using analog integrated circuits designed by experts with good characteristics, it relieves circuit designers of the burden of designing from the base of transistors.

IC can integrate analog and digital circuits on A single chip to make devices such as analog to Digital converter (A/D Converter) and digital to analog converter (D/A Converter). This circuit offers smaller size and lower cost, but must be careful about signal collisions.
