    • A testing mode is provided for self testing of the transmitter and receiver pair provided on-chip. The testing mode targets each module individually; wherein when one of the two devices is placed under test, the other is used as a tester. When the transmitter is the device under test and the receiver is the tester that receives a transmitted signal from the transmitter, the receiver is used to determine the data eye size with the transmitted signal. When the receiver is the device under test and the transmitter is the tester, the transmitter is used to determine the amount of noise and power loss tolerated by the receiver.
    • 为片上提供的发送器和接收器对的自检提供测试模式。 测试模式分别针对每个模块; 其中当两个装置中的一个被放置在被测试时,另一个被用作测试器。 当发射机是被测设备时,接收机是从发射机接收发射信号的测试仪,接收机用于利用发射信号确定数据眼睛尺寸。 当接收机是被测设备,发射机是测试仪时,发射机用于确定接收机所容忍的噪声和功率损耗。
