The LTC488ISW#PBF is a differential bus transceiver, especially designed for USB and Digital video applications. It is powered by a voltage range from 3.3 V to 5.5 V. The device is equipped with output drivers that buffer both the upstream and downstream data bus signals. The LTC488ISW#PBF has several features that make it suitable for a wide range of high-speed data communication applications.

Application Field

The LTC488ISW#PBF is mainly used in high-speed data communication applications including Digital Video Interface(DVI), Universal Serial Bus(USB) and small form-factor pluggable/ fiber channel applications. It can also be used for other applications requiring high-speed data throughput over short lengths of cable.

The device is ideal for Video Interface, PC/PCI/ISA connections, and multi-point Serial Bus Applications. It is also suitable for applications requiring data throughput from 100 Mbps to 6.25 Gbps.

Features

The LTC488ISW#PBF has several features that make it suitable for high-speed data communication applications:

• Low power consumption
• High data rate (up to 6.25 Gbps)
• High DC level tolerance of external components
• High speed serial outputs
• Output drivers that buffer the upstream and downstream data bus signals
• Differential Bus Transceiver with Programmed De-emphasis & Equalizer
• Digital level control output signal

Working Principle

The LTC488ISW#PBF works by taking an input of a differential signal from the upstream source, and transmitting it downstream to the receiving device, performing a 1:1 signal replication. The device features a differential Bus Transceiver for upstream and downstream data signals, with a Programmable De-emphasis and Equalizer, which help to reduce signal distortion on the bus.

The device also features an Output Driver which supplies active impedance at the termination of the receiver line. The device also features a Digital Output Driver, which drives an internal digital switch to control the output signal level. This provides a reliable digital level control for the signal.

The device also has a Low Power Mode, allowing it to operate at lower power levels when in Idle mode. This feature helps to reduce system power consumption, and increases efficiency and battery life.

Conclusion

The LTC488ISW#PBF is a high speed, low power differential bus transceiver, specifically designed for USB and Digital Video connections. It is ideal for applications such as Video Interface, PC/PCI/ISA connections, and multi-point Serial Bus Applications. The device also features an Output Driver, a Programmable De-emphasis and Equalizer, and a Digital Output Driver. These features make the LTC488ISW#PBF suitable for a wide range of high-speed data communication applications.
