Description
General part information
SN65EPT21 Series
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.
The VBBpin is a reference voltage output for the device. When the device is used in single-ended mode, the unused input should be tied to VBB. 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 VCCand VBB. Also limit the sink/source current to < 0.5 mA to VBB. Leave VBBopen when it is not used.
The SN65EPT21 is housed in an industry standard SOIC-8 package and is also available in an optional TSSOP-8 package.
