SP207EDS/09

SP207E Series High Performance Transceivers

For the Human Body Model, the current limiting

resistor (R

S) and the source capacitor (CS) are

1.5k

Ω an100pF,respectively. ForIEC-1000-4-2,

the current limiting resistor (R

S) and the source

capacitor (C

S) are 330Ω an 150pF, respectively.

The higher C

S value and

lower R

S value in the

IEC1000-4-2 model are more stringent than the

Human Body Model. The larger storage capacitor

injects a higher voltage to the test point when SW2

is switched on. The lower current limiting resistor

increases the current charge onto the test point.

Table 4. EIA Standard Definitions

EIA STANDARDS

The Electronic Industry Association (EIA)

developed several standards of data transmission

which are revised and updated in order to meet

the requirements of the industry. In data

processing, there are two basic means of

communicatingbetweensystemsandcomponents.

The RS--232 standard was first introduced in

1962 and, since that time, has become an

industry standard.

Table 3. Transceiver ESD Tolerance Levels

The RS-232 is a relatively slow data exchange

protocol, with a maximum baud rate of only

20kbps, which can be transmitted over a

maximum copper wire cable length of 50 feet.

The SP207E through SP213E Series of data

communications interface products have been

designed to meet both the EIA protocol

standards, and the needs of the industry.
