The Evaluation board for the AD5110 contains a SDP connection and software which allows the AD5110 to be controlled from an SDP board. This evaluation board requires an SDP Controller board for connection to the PC. The SDP controller board connects to the PC via USB 2.0. The evaluation board will connect to the SDP controller board. The evaluation board cannot be connected directly to the PC. The evaluation software running on the PC will communicate with the evaluation board through the SDP Controller board.

If you have not previously purchased an SDP Controller board, please do so to ensure a full evaluation setup.

The HMC959LC3 is a Divide-by-4 with Reset designed to support clock frequencies as high as 26 GHz. During normal operation, with the reset pin not asserted, the output toggles from its prior state on the positive edge of the clock. This results in a divide-by-four function of the clock input. Asserting the reset pin forces the Q output low regardless of the clock edge state (asynchronous reset assertion). Reversing the clock inputs allows for negative-edge triggered applications. The HMC959LC3 also features an output level control pin, VR, which allows for loss compensation or for signal level optimization.All input signals to the HMC959LC3 are terminated with 50 ? to ground on-chip, and may be either AC or DC coupled. Outputs can be connected directly to a 50 ? terminated system, while DC blocking capacitors may be used if the terminating system is 50 ? to a non-ground DC voltage. The HMC959LC3 operates from a single -3.3 V DC supply and is available in a ceramic RoHS-compliant 3?3 mm SMT package.APPLICATIONS High Speed Frequency Divider?(up to 26 GHz) Broadband Test & Measurement Clock Synthesis Phase Locked Loops
