CDC3S04EVM评估模块（EVM）旨在展示CDC3S04的电气性能。DescriptionThe CDC3S04 is a four-channel low-power sine-wave clock buffer. It can be used to buffer a single mastern clock to multiple peripherals. The four sine-wave outputs (CLK1–CLK4) are designed for minimal channel-to-channel skew and ultralow additive output jitter. Each output has its own clock request input which enables the dedicated clock output. These clock requests are active-high (can also be changed to be active-low via I2C), and an output signal is generated that can be sent back to the master clock to request the clock (MCLK_REQ). MCKL_REQ is an open-source output and supports the wired-OR function (default mode). It needs an external pulldown resistor. MCKL_REQ can be changed to wired-AND or push-pull functionality via I2C. This evaluation module (EVM) is designed to demonstrate the electrical performance of the CDC3S04. For optimum performance, the board is equipped with 50-ohm SMA connectors and well controlled 50-ohm impedance microstrip transmission lines.Features
