serdes applications

applications such as SONET/SDH, there is no limit to the jitter of the recovery clock, nor too much. 3. Switching power supply switching frequency is generally less than the loop bandwidth, can be traced by the CDR. However, while the noise on the switching power supply coupled to the VCO (Digital to multi-phase convertor) cannot be traced by the loop, the low cost ring VCO is particularly sensitive to power supply noise. On the other hand, the switc

Recently, when debugging a board, it was found that the network port cannot be pinged when the board is restarted after power loss. It uses a 2041 film. When locating the problem, it is found that the serDes register Initialization is incorrect. After the first operation, the err bit is 1 and the done bit is 0. After the CPU is reset without power loss, the err bit becomes 0, if the done bit is changed to 1, Ping is normal. According to the symptom an

First, why use SerDes Traditional source synchronous transmission, clock and data separation. At low rate (When the rate gets higher, it's going to be a problem.Because the transmission line delay inconsistency and jitter exists, the receiver can not correctly sampled data, to the point of the forbidden Eye graph.Then I thought about recovering the clock from the data to sample the data, the CDRThus there is no delay inconsistency, and a slight jitte

Visit m. baidu. comxs on a tablet such as an ipad, and you will also see that the interface is dazzling and will not be lost to nativeapp. In the desktop application field, native applications have lost to webapps. If html5 is more mature in the future, will nativeapp also lose to webapps in the mobile application field?

Sometimes our applications need to invoke applications that others have already written (provided that they are already installed on the user's phone). Their application a calls their own application B, there are more methods, for example, in the activity of the invoked application B, set Intent-filter, and then use the intent call directly. After that, let's talk about how to invoke a third party applicati
