AD8148: Triple Differential Driver for Wideband Video

The AD8146/AD8147/AD8148 are high speed triple, differential or single-ended input to differential output drivers. The AD8146 and AD8147 have a fixed gain of 2, and the AD8148 has a fixed gain of 4. They are all specifically designed for the highest resolution component video signals but can be used for any type of analog signals or high speed data transmission over either Category 5 UTP cable or differential printed circuit board (PCB) transmission lines.

AD8147: Triple Differential Driver for Wideband Video

The AD8146/AD8147/AD8148 are high speed triple, differential or single-ended input to differential output drivers. The AD8146 and AD8147 have a fixed gain of 2, and the AD8148 has a fixed gain of 4. They are all specifically designed for the highest resolution component video signals but can be used for any type of analog signals or high speed data transmission over either Category 5 UTP cable or differential printed circuit board (PCB) transmission lines.

AD8145: High Speed, Triple Differential Receiver with Comparators

Product Description

The AD8145 is a triple, low cost, differential-to-single-ended receiver specifically designed for receiving red-green-blue (RGB) video signals over twisted pair cable or differential printed circuit board traces. It can also be used to receive any type of analog signal or high speed data transmission. Two auxiliary comparators with hysteresis are provided that can be used to decode video sync signals that are encoded on the received common-mode voltages, to receive digital signals, or as general-purpose comparators. The AD8145 can be used in conjunction with the AD8133 or AD8134 triple differential drivers to provide a complete low cost solution for RGB over Category 5 UTP cable applications, including KVM.

AD8120: Triple Skew-Compensating Video Delay Line with Analog and Digital Control

Product Description

The AD8120 is a triple broadband skew delay compensation IC that corrects for time mismatch of video signals incurred by transmission in unshielded twisted pairs of Category-5 and Category-6 type cables. Skew between the individual pairs exists in most types of multi-pair UTP cables due to the different twist-rates used for each pair in order to minimize crosstalk among the pairs. Some pairs are therefore longer than others, and in long cables, the difference in propagation time between two pairs can be well into the tens of nanoseconds.

AD8123: Triple Differential Receiver with Adjustable Line Equalization

Product Description

The AD8123 is a triple, high speed, differential receiver and equalizer that compensates for the transmission losses of UTP and coaxial cables up to 300 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Logic circuitry inside the AD8123 controls the gain functions of the individual stages so that the lowest noise can be achieved at short-to-medium cable lengths. This technique optimizes its performance for low noise, short-to-medium range applications, while at the same time provides the high gain bandwidth required for long cable equalization (up to 300 meters). Each channel features a high impedance differential input that is ideal for interfacing directly with the cable.
