Skew between the individual pairs exists in most types of multipair UTP cables due to the different twist rates that are used for each pair to minimize crosstalk between pairs. For this reason, some pairs are longer than others, and in long cables, the difference in propagation time between two pairs can be well into the tens of nanoseconds. The AD8120 contains three delay paths that provide broadband delays up to 50 ns, in 0.8 ns increments, using 64 digital control steps or analog control adjustment. The delay technique used in the AD8120 minimizes noise and offset at the outputs. The bandwidth of the AD8120 ranges from 150 MHz to 200 MHz, depending on the delay setting. This wide bandwidth makes the AD8120 ideal for use in applications that receive high resolution video over UTP cables. The logic circuitry of the AD8120 provides individual delay con- trols for each channel. The delay times are set independently using a standard 4-wire SPI bus or a standard I2C bus, or by applying analog control voltages to the VCR, VCG, and VCB pins. Analog control offers a simple solution for systems that do not have digital control available. The AD8120 is designed to be used with the AD8123 triple UTP equalizer in video over UTP applications, but it can also be used in other applications where similar controllable broadband delays are required. The AD8120 is available in a 5 mm × 5 mm, 32-lead LFCSP and is rated to operate over the industrial temperature range of −40°C to +85°C. FUNCTIONAL BLOCK DIAGRAM R d G B d d Figure 1. |
