DESCRIPTION

The SN65EPT21 is

a differential PECL-to-TTL

translator. It operates on +3.3 V supply and ground

only. The device includes circuitry to maintain inputs

at Vcc/2 when left open.

Table 1. Pin Descriptions

FUNCTION

The V_BBpin is a reference voltage output for the

device. When the device is used in single-ended

mode, the unused input should be tied to V_BB. This

reference voltage can also be used to bias the input

when it is ac coupled. When it is used, place a

0.01μF decoupling capacitor between V_CCand V_BB

Also limit the sink/source current to < 0.5 mA to V_BB

Leave V_BBopen when it is not used.

No Connect

(DFN8 only) Thermal exposed pad must be

connected to a sufficient thermal conduit.

Electrically connect to the most negative supply

(GND) or leave unconnected, floating open.

The SN65EPT21 is housed in an industry standard

SOIC-8 package and is also available in an optional

TSSOP-8 package.
