摘要: Devices and methods for serial loopback testing in an integrated circuit (IC) are provided. To implement testing, equalizer stage of a receiver the IC is powered down. In addition, common-mode voltage reduced and/or bulk node connected to ground. Doing so may reduce impact capacitive coupling from input pins buffer, thereby improving quality output signal.
