NC7WZ125K8X Application Field and Working Principle

NC7WZ125K8X is a small size low voltage, low power CMOS 5-bit differential bus transceiver which is classified under Logic - Buffers, Drivers, Receivers, and Transceivers. It provides differential transmit/receive functions for the use in applications such as dual speed Ethernet, RS-485, and LVDS communications.The NC7WZ125K8X has excellent noise immunity with very fast switching speed. The transceiver has output drivers (in transmitter mode) and input receivers (in receiver mode) that feature an LVTTL logic-compatible hysteresis range. The transceiver also has very low propagation delay. The envelope of the output signal does not degrade even when driving an increased capacitive load. It has a wide operating temperature of -40C to +125C and it consumes a low static current of 5.8 mA. With a high power supply voltage of 4.5 V to5.5 V, it can drive up to 4.5 V to 5.5 V.In working principles, the NC7WZ125K8X differential bidirectional transceiver receives an input signal of differential voltage, characterizes that voltage, and outputs either the same data or an inverted form of the input voltage. The driver presents the data with active low and active high output wave forms to reduce the possibility of bus line contention. The receiver has an exponential voltage to time conversion and a pair of inputs with a hysteresis range of 5-15mV. This feature allows the transceiver to recognize the logic levels accurately.The NC7WZ125K8X transceiver can be connected to a serial network to provide a full-duplex communication channel that can support user-defined data rates. It can be used in a variety of applications, such as Ethernet, LVDS, and RS-485, by implementing the application appropriate electrical environment.The NC7WZ125K8X is suitable for applications that have aggressive timing requirements for communications protocol switching. Its low-voltage operation and low dissipation make it an ideal solution for low power and space-constrained designs. The thermal regulation feature of the device protects itself from damage due to excessive power dissipation. Its gradual thermal regulation allows for greater stability in the output waveforms even under excessive thermal conditions.The NC7WZ125K8X family of transceivers is part of a broad portfolio of bus interface ICs from ON Semiconductor. The company provides products that enable simple, cost effective implementation of industry accepted protocols such as FireWire, PCI Express, USB, DisplayPort, and Serial RapidIO. All of these products feature low power, operation speeds of up to 12.5 Gbps, jitter attenuation, and EMI/RFI rejections.The ON semiconductor bus interface IC portfolio provides support for a variety of applications and system configurations. This includes desktop, notebook and mobile computers and peripherals, consumer electronic devices, instrumentation, industrial automation, medical imaging, and telecom/networking systems. For these applications, there are a variety of interface protocols, such as PCIe, SATA, USB and Ethernet, as well as legacy and emerging protocols.The NC7WZ125K8X transceiver from ON Semiconductor offers a cost-effective solution for low-power differential communication applications. It has low-voltage operation for energy-efficient designs and a robust thermal regulation feature for greater output waveform stability. It is designed for systems requiring fast switching and excellent noise immunity, making it an ideal candidate for dual speed Ethernet, RS-485, LVDS, and FireWire applications.
