Advanced Settings
In addition to the basic settings provided in the TX basic
control registers, advanced settings are available in TX Drive 0
Control and TX Drive 1 Control registers (Address 0x30 to
Address 0x4F). The advanced settings are useful in applications
where each output requires an individually programmed
preemphasis or output level setting beyond what is available
in the lookup table in basic mode. To enable these advanced
settings, set the TX CTL SELECT bit in the TX basic control
register to a logic high. Next, program the TX Drive 0 control
and Drive 1 control registers (Address 0x30 to Address 0x4F) to
the desired output level and boost values. A subset of possible
settings is provided in Table 13. An expanded list of available
settings is shown in Table 19 in the Applications Information
section. These advanced settings can also be used to modify the
TX lookup table settings (Address 0x60 to Address 0x6F). The
advanced settings register map is shown in Table 15.
The preemphasis boost equation follows.
