The ADG1633 and ADG1634 are monolithic industrial CMOS (iCMOS®) analog switches comprising three independently selectable single-pole, double-throw (SPDT) switches and four independently selectable SPDT switches, respectively.
All channels exhibit break-before-make switching action that prevents momentary shorting when switching channels. An EN input on the ADG1633 (LFCSP and TSSOP packages) and ADG1634 (LFCSP package only) is used to enable or disable the devices. When disabled, all channels are switched off.
The ultralow on resistance and on-resistance flatness of these switches make them ideal solutions for data acquisition and gain switching applications, where low distortion is critical. iCMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery-powered instruments.

The AD-SYNCHRONA14-EBZ is an ideal self-contained device to use in evaluation and prototyping of applications that need a highly accurate frequency and phase-controlled source clock. It is designed around the Analog Devices AD9545 and HMC7044 and greatly simplifies clock distribution and multi-channel synchronization in complex systems. It is intended to be used by trained professionals in a laboratory environment, and not intended as an end product for commercial use. It can be taken as a complete reference design and customised as required for any end customer applications. Full design details are made available free of charge.
The AD-SYNCHRONA14-EBZ comes in a 1U mechanical form factor. Using popular industry connector SMA and TwinAX interfaces most labs will already have the needed cables.
With its internal OCXO it can operate in standalone mode or be fed from a choice of external sources, such as 3 separate high speed differential clock inputs, a 10MHz reference and 1PPS. This flexibility combined with the capability to select either of the internal VCXO options of 100MHz or 122.88MHz, gives almost unlimited choice for the frequency of interest and accuracy needed for a wide variety of application areas.

The EVAL-24TSSOPEBZ evaluation board evaluates 24-lead TSSOP devices in the Switches and Multiplexers Portfolio that are purchased separately. A clamp is supplied with the EVAL-24TSSOPEBZ to secure a 24-lead TSSOP device to the evaluation board without the need for soldering, making the board reusable for multiple devices.
A 24-lead TSSOP device can be clamped or soldered to the center of the evaluation board. Each pin of the device has a corresponding link from K1 to K24 that can be set to either VDD or GND. A wire screw terminal supplies VDD and GND. SMB connectors on the board allow additional external signals to be supplied to the device. In addition, there is space available at the top of the board for prototyping.
Full specifications of the device under test (DUT) are available in the corresponding product data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
