2 General Description

The LMK1D1208I is an I2C-programmable clock buffer that delivers 8 differential LVDS outputs. This device has two universal input buffers which support differential or single-ended clock inputs that can be selected through I2C programming. The device also features on-chip bias generators that can provide LVDS common-mode voltage for AC-coupled differential clock inputs.

The I2C capabilities of this device can be evaluated by connecting a micro-USB cable to the computer and interfacing with the TICS Pro software.

This fully assembled and factory-tested evaluation board allows complete validation of device functionalities. For optimum performance, the board is equipped with SMA connectors and well-controlled, 50-Ω impedance, microstrip transmission lines.
