The 32-lead LFCSP_SS package requires thermal trace squares

and thermal vias to an embedded ground plane in the PCB. The

exposed paddle must connect to ground for proper operation to

data sheet specifications. Refer to JEDEC standard JESD51-5 for

more information.

TEST CIRCUITS AND SWITCHING

CHARACTERISTICS

Figure 19 shows a line driver voltage measurement circuit of the

differential line driver and receiver AP/AN and BP/BN pins.

OUTPUT DRIVE CURRENTS

Figure 20 through Figure 25 show typical current voltage char-

acteristics for the output drivers of the transceiver. The curves

represent the current drive capability of the output drivers as a

function of output voltage. Drive Strength 0 is DS0, and Drive

Strength 1 is DS1.

ESD (electrostatic discharge) sensitive device.

Charged devices and circuit boards can discharge

without detection. Although this product features

patented or proprietary protection circuitry, damage

may occur on devices subjected to high energy ESD.

Therefore, proper ESD precautions should be taken to

avoid performance degradation or loss of functionality.
