E1XC EVALUATION DAUGHTERBOARD

E1XC
Two E1XCs can be socketed into the daughterboard. Each is individually accessible
and can run independently of the other. All pins except for the microprocessor
interface and power pins are connected to header strips for easy test equipment
access. Analog receive power pin RAVD is connected to a jumper to enable tying to
either ground or power. Tying this pin to ground will disable the internal RSLC TSB,
reducing the power consumed. Tying the RAVD pin to VCC enables the normal
operating mode. All other power pins are appropriately decoupled and all inputs are
tied high through 10 kΩ resistors SIPs.
For a more detailed description of the E1XC and its features, refer to the E1XC
Standard Product datasheet.
6.5
"CSU" DIPs and Jumpers
Normally, the two E1XCs run independently of each other except when explicit
connections are made between the two devices. To facilitate testing of a simple
application involving two devices appropriate control signals have been wired to two
16 pin DIP sockets and six jumpers to enable hooking up the E1XCs in a "CSU"-like
application.
