Evaluation Support
The EV9730 is an Evaluation Kit designed for evaluating and demonstrating the capabilities of the CMX973 integrated circuit.
All the circuits necessary to demonstrate the facilities provided by the IC, such as matching circuits, power supply regulators,
etc. are provided on the EV9730 board.
A C-BUS serial interface connector is provided for control of the EV9730 by a host microcontroller or CML PE0002 interface
card. Alternatively any microcontroller evaluation/emulator kit can be used to drive the CMX973/EV9730 serial bus.

Depending on the method of lead termination at the edge of the package, pull back (L1) may be present.
L minus L1 to be equal to, or greater than 0.3mm
The underside of the package has an exposed metal pad which should ideally be soldered to the pcb to enhance the thermal
conductivity and mechanical strength of the package fixing. Where advised, an electrical connection to this metal pad may also
be required
