There are totally 31 steps, each step with 2ns difference, for adjusting the delay between each color individually. Then the graphics quality can be further assured.

The average cost of 100 meters of CAT-5 cable is $20 while the average cost of 100 meters of coax cable could easily exceed $240. Furthermore, wiring is reduced from a bulky bundle of cables to 1 easily pulled cable. Let us also have a look at the characteristics of CAT-5 type cable before we go deeper on the topic.
- Page 10 Common Video Problems (Ref. Intersil) hosting Ghosting always occurs horizontally and to the observer’s right following the path of the video signals. To avoid reflections and maintain integrity of the input video signals over long CAT-5 cables, each stage must be properly terminated. Common-mode Noise Common mode noise can cause a loss of synchronization because the sync signals are typically transmitted common-mode.
- Page 11 Common Video Problems (Ref. Intersil) olor Mismatch Color mismatch is the effect of a difference in gain or offset of the color channels. Example shows the screen on the bottom has excess blue. Power Supply Noise Power supply noise appears as a repetitious disturbance in the video picture. Use a higher quality voltage regulator to power the amplifiers and bypass all chipsets as close to the power pins as possible.
- Page 12 hannel Timing Mismatch If the R, G, and B signals are mismatched with respect to time, they will cause a blurring of the signal. An integrated solution is available, CV-909 is designed to overcome this mismatch! Smearing Equalization issues are necessary when using CAT-5 cables to transmit VGA signals. Compensation is needed to rectify the high frequency losses of the system.
- Page 13 Since the lossless transmission is impossible for such a kind of converters, there are a couple of key factors while evaluating these modules. First of all, it is about the signal bandwidth. Fundamentally, the higher the bandwidth, the better it is supposed to be. Secondly, the slew rate! The slew rate represents the maximum rate of change of a signal at any point in a circuit.
- Page 14 Due to the limited pairs of wires of CAT-5 cables, VGA and H/V sync signals are basically mixed into 3 pairs of differential signals over 3 out of 4 pairs in the cable. The fourth pair of wires of CAT-5 cables is usually served as the audio or RS-232 channel. Based on the distinct technologies to achieve this goal, the audio transmission distance varies.
- Page 15 The SELLER warrants the ARD-1000 VGA & RS-232 over CAT5 Extender with RGB Delay Control to be free from defects in the material and workmanship for 2 year from the date of purchase from the SELLER or an authorized dealer. Should this product fail to be in good working order within 2 year warranty period, The SELLER, at its option, repair or replace the unit, provided that the unit has not been subjected to accident, disaster, abuse or any unauthorized modifications including static discharge and power surges.
