1.0625Gbps to 11.3Gbps,
SFP+ Dual-Path Limiting Amplifier
General Control Register (MODECTRL)
Bits 7 to 0: MODECTRL[7:0]. The MODECTRL register enables a switch between normal and setup modes. The setup
mode is achieved by setting this register to H0x12. MODECTRL must be updated before each write operation.
LOS Timer Setting Register (SET_LOSTIMER)
Bits 6 to 0: SET_LOSTIMER[6:0]. The SET_LOSTIMER register is a 7-bit register that can be set from 0 to 127. See
the Typical Operating Characteristics section for a typical timer period vs. DAC code.
