VBB 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 VBB pin 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 …
