This document contains a circuit diagram for a control block and DC-DC converter. The control block diagram shows the connections between various input, output, and control pins of an integrated circuit. It includes labels for components like resistors, capacitors, diodes, and pins for signals like RXIN, RXCLK, LVDS, and more. The DC-DC converter diagram shows connections for an IC that regulates voltages like V12in, V1D2, V3D3, VGHC and includes components like an inductor and diode.
