ELECTRICAL SPECIFICATIONS

*CAUTION*

This product incorporates numerous static-sensitive components.

Always wear an ESD wrist strap and observe proper ESD handling

procedures when working with this device. Failure to observe this

precaution may result in module damage or failure.

damage to the device. Furthermore, extended operation at these maximum

ratings may reduce the life of this device.

1. *CRITICAL* In order to operate the device over this range it is necessary for a 200

Ω resistor to be

placed in series with Vcc.

2. Potential rate of data recovered on the DATA line (pin 10). The decoder rate is internally fixed at about

2kbps.

3. When operating from a 5V source it is important to consider that the output will swing to well less than 5

volts as a result of the required dropping resistor. Please verify that the minimum voltage will meet the

high threshold requirement of the device to which data is being sent.

4. Vcc referenced to voltage on the Vcc pin, after dropping resistor

5. For a BER of 10-5 at 4800 baud. Sensitivity is affected by antenna SWR.

6. Time to valid data output.

7. Maximum drive capability of data outputs.

PERFORMANCE DATA

These performance parameters are

based on module operation at 25°C

from

a

3.0VDC

supply

unless

otherwise noted. Figure 2 at the right

illustrates

the

connections

necessary for testing and operation.

It is recommended all ground pins

be connected to the groundplane.

The pins marked NC have no

electrical

connection

and

are

designed only to add physical

support.
