Operating Modes

The TLK10232 is a versatile high-speed transceiver device that is designed to perform various physical

layer functions in three operating modes: 10GBASE-KR Mode, 1G-KX Mode, and General Purpose (10G)

SERDES Mode. The three modes are described in three separate sections. The device operating mode is

determined by the MODE_SEL and ST pin settings, as well as MDIO register 1E.0001 bit 10.
