BCM5464A1KRBG-Ethernet Transceivers

The Gigabit Ethernet transceivers operate at the physical layer of the OSI network model. The purpose of the ethernet transceivers is to implement the hardware, send and receive functions of the Ethernet frames, and provide analog signal physical access to the vital link. It implements the physical layer part of the Ethernet and interfaces between the digital realm of link-layer packet signaling and Ethernet's line modulation. The ethernet transceivers are interfaced with a Media Independent Interface (MII) to a MAC chip in a microcontroller or another system that takes care of the higher layer functions.

The BCM5464A1KRBGconsists of a single monolithic CMOS on which four complete 10/100/1000BASE-T Gigabit Ethernet transceivers are integrated. The BCM5464 offers high port density applications by striving for low-power and small footprint sizes. The BCM5464 provides a new class of cost-effective Gigabit Ethernet equipment by lowering system cost and reducing power dissipation by nearly 25%. The BCM5464's achieve robust and low-power operation by combining digital signal processor-based architecture and advanced power management techniques. The BCM5464 reduces the design constraints required to meet EMI radiations because it has the lowest operating power in the industry. The working capacity of the BCM5464 is 750 mW per port.

The BCM5464A1KRBG supports the GMII, SerDes MAC interfaces, RGMII and SGMII. The BCM5464 board eliminates the trace delays required by the RGMII specification by adjusting the RGMII clock timing. The reduced pin count interfaces reduce the number of layers needed to route high-density solutions, simplify design and lower the overall cost of the system. In addition, these interfaces reduce the MAC/ switch cost by allowing fewer pins at the MAC/switch. The fewer pins at the MAC/switch enable smaller die sizes than possible with full GMII. The 0.13-µm process of the BCM5464 offers the best performance, lowest cost, and lowest power for Gigabit copper solutions. The BCM5464 provides an excellent long-term cost curve, enabling better cost reduction over time without redesigning or requalifying any section of the BCM5464A1KRBG. Every port of the BCM5464 is entirely independent. The ports of the BCM5464  has an individual interface, control, and status registers and incorporates several advanced features

One of the prominent features of the BCM5464 is that it prevents CESD events. CESD is an issue that has become more common with recent cable installations. It is an ESD event that occurs when an electrically charged cable is plugged into a network port. The BCM5464 can tolerate over 4 kV of CESD, which is well above typical industry standards. This prevents ESD damage not only during manufacturing but during CESD events in the field.

The main applications of ethernet transceivers are in the field of communication. The features and characteristics of the BCM5464 make it an ideal candidate in all types of applications that involves a large amount of data transport at lightning speeds.

TL1963AQKTTRQ1

Image
  The TL1963AQKTTRQ is a low-dropout (LDO) regulator that is designed for the fast transient response. With a dropout voltage of 340 mV, the device can deliver 1.5 A of output current. The operating quiescent current is 1 mA, and in shutdown, it drops to less than 1 mA. The output voltage ranges between 1.21 and 20 volts. Quiescent current is well-controlled; unlike many other regulators, it does not rise in dropout.The TL1963AQKTTRQ regulators feature a low output noise and fast transient response, making them excellent for sensitive RF supply applications. With output capacitors as low as 10 F, the TL1963AQKTTRQ regulators are stable. Small ceramic mlcc capacitors can be employed instead of ESR, as is the case with most other regulators. In TL1963AQKTTRQ voltage regulators, reverse-battery protection, current limiting, heat limiting, and reverse-current protection are all built into the internal protection circuitry.Fixed output voltages of 1.5 V, 1.8 V, 2.5 V, and 3.3 V are availab

SN65HVD485EDGKR (transceiver)

Image
  A transceiver is a transmitter/receiver that exists in a single box. Whereas the phrase is most commonly associated with wireless communications equipment, it can also refer to transmitter/receiver devices in cable or optical fiber networks. This electrical device's primary function is to broadcast and receive various signals. The transceiver in radio communications can operate in half-duplex or full-duplex mode: half-duplex transceivers It can transmit or receive data, but not at the same instant. This is because the sender and receiver are linked to the same antenna through an electrical switch. This method is commonly used in ham radios, walkie-talkies, as well as other single-frequency Full-duplex transceivers. The radio transmitter and receiver can operate in tandem. Various radio frequencies are used for transmission and receiving. This mode may be found in both portable and cellular two-way radios. Full duplex is more efficient but the significance of both networks is de
