This application note describes the implementation of an ITU-T G.987- and ITU-T G.989-compliant fractional burst clock data recovery (BCDR) circuit for an optical line termination (OLT) unit operating at 1.25 and 2.5 Gb/s in a passive optical network (PON), such as G-PON, XG-PON1, NG-PON2, and 10G EPON [Ref 1].
Note: For standards and PON terms, see References.
