A catheterization laboratory or Cathlab is an examination room in a hospital that offers a variety of diagnostic and interventional cardiology procedures used in the treatment of coronary artery and peripheral vascular diseases. The diagnostic imaging equipment of the Cathlab is used to visualize the arteries and chambers of the heart and treat any stenosis found. In the Cathlab data is send through optical fiber cable to the acquisition computer. The acquisition computer consists of digital processing board. Optical cable from x-ray detector is connected to the detector interface and processing board (DIPB). This board uses an optical transceiver to convert optical data into digital data. As the transceiver data is serial this is converted into parallel data using SerDes chip. This is fed to FPGA for imaging processing. The SerDes chip VSC7145 used to convert serial data into parallel data is obsolete and no more available for manufacturing. There is no direct replacement of this part. This paper explains an alternate all digital design for SerDes chip that to be used in the cathlab system.
