• Bypass Enable/Disable: the device can configure the input to bypass the internal module
and to go to the output directly which may be useful during test phase.
• Loop Bandwidth Control: the device can configure the Loop bandwidth of ranges 20MHz to
40MHz.
• Output Swing Control: the typical output swing range is in 385 mV
ppD
~ 1050 mV
ppD
in ten
steps.
• Output Mute Override: the output can be muted with an override enable/disable option.
• Output De-emphasis: Depending on the channel characteristics, the output de-emphasis
level can be adjusted. The post-tap de-emphasis range is 0 ~ 350 mV
ppD
and the pre-tap de-
emphasis range is 0 ~ 350 mV
ppD.
• Output Polarity Invert: The output signal polarity can be inverted with a register setting.
• Loss-of-Lock (LOL): The status of the PLL lock is visible through a register.
