 29 Apr 2006 3:15 the bandwidth of LA(limiting amplifier) |
|
|

|
| Hi, friends, I have some doubts in the decision of the bandwidth of the LA (limiting amplifier). I've been told that 0.8 times of data speed is enough, a higher bandwidth will introduce more nosie. However, I also read in some books and paper that 1.0 to 1.2 times of data speed is the standard. So, which one is right? And are there any standards?

| Operating from a single 3.3V supply, the MAX3274 features a 10mV input sensitivity while consuming less than 260mW. The limiting amplifier provides a bandwidth of 1.7GHz for 2Gbps operation and 890MHz for 1Gbps operation. |

| Dear IanP, do you mean that the requirement of bandwidth can vary according to the system arrangement? For example, with a 4-order Bessel filter, 0.8 times of data speed would also be enough, right?
