A dual-channel transmitter ASIC LOCx2 have been designed and produced. In order to ensure all the LOCx2 chips behave properly, a Quality Assurance needs to be conducted before assembly. The problem I was trying to solve in this project is to yield a clock signal with continuously adjustable frequency and phase offset to generate and control an eye diagram for the QA.
