Evaluation and demonstration boards and kits are core components in the design process of new products, because they allow designers to acquire data from their circuits, test for functionality and ensure robustness when connected to other parts. This article looks at the SI5332-12EX-EVB and its application fields and working principle.

The SI5332-12EX-EVB is a complete evaluation, demonstration, and application development board for the Si5332 12-channel differentially-output universal clock fanout buffer from Silicon Labs. This board is powered with an external +5V supply and is provided with a 3.3V secondary power supply. The board utilizes 3 on-board LEDs for status indication of the eleven outputs of the Si5332 device, making it ideal for logic analysis and fault diagnosis. There are also 11 termination jumpers on board which allow for customization of termination, and variable input signal frequency can be made possible by using the on-board DIP switches.

The SI5332-12EX-EVB is mainly used for clock design and testing, as well as developing jitter and skew immunity systems. It offers a number of features and advantages to users. For starters, the board accommodates both LVPECL and LVDS clock input signals for testing and evaluation, which allows users to have greater flexibility when designing and testing circuits. Additionally, the board also offers enhanced synchronization and jitter reduction through its highly-precise skew trimming capabilities. Lastly, the 11 outputs can be adjusted for any combination of LVPECL, LVDS, and LVCMOS, offering an incredibly versatile platform for application development and testing.

The working principle of the SI5332-12EX-EVB is simple. When external power is applied to the board, the two inputs are supplied with a clock signal from either a 14-pin DIP switch or a 50-ohm termination jumper. The onboard Si5332-12 universal clock fanout buffer then splits and amplifies each signal to produce 11 outputs, 10 of which are configurable to either LVPECL, LVDS, or LVCMOS. The 11th output can be configured in the frequency range of 5.5 to 50 MHz for any of the three output standards as well, depending on the user’s needs. This allows the board to be used in a variety of applications that require clock signal amplification and splitting.

As a whole, the SI5332-12EX-EVB is a powerful evaluation and demonstration board that is ideal for conducting tests and experiments involving clocks, skew, jitter, and synchronization issues. It offers users a great deal of flexibility when designing and testing circuits, and is well suited for a variety of applications where clock signal amplification and splitting is required. Its simple working principle and ease of use make it an indispensable tool for anyone involved in clock design and development.
