EV9930 EvKit

CML Microcircuits has introduced an evaluation kit (EvKit), for their CMX993 RF quadrature modulator IC.

The CMX993 is a highly integrated, general purpose, RF quadrature modulator, offering 100MHz to 1GHz operation and excellent wide-band noise performance, says CML. The EV9930 EvKit provides a platform for the evaluation of this device. The design engineer can achieve rapid and full evaluation of the CMX993, using the EV9930 (which is a fully populated board), giving access to all of the device's RF, base band and control signals by either connectors or test points. These test access points are available to accept common test equipments such as RF and base band signal generators and also spectrum analysers.

Control of the CMX993 is by on-chip registers, which are accessible over the C-BUS interface (similar to an SPI serial interface). A PE0002 interface card (not supplied, but available from CML), allows the C-BUS interface to be controlled from a PC, via its USB port. Alternatively, the C-BUS interface can be controlled by an external microprocessor.

The EV9930 base band inputs can be configured to work with CML's CMX910 base band processor (AIS) or the CMX981 base band processor (digital radio), standard test equipment or with a custom base band system.

The EV9930 is available now.
