The GAIN pin can be used to set the overall datapath flat gain (broadband gain including high frequency) of the SN75LVPE5412 when the device is in Pin Mode. The pin GAIN sets the Flat-Gain for all channels. In I2C Mode each channel can be independently set. Table 6-3 shows flat gain control configuration settings. The default recommendation for most systems will be GAIN = L4 (float) that provides flat gain of 0dB.
The flat gain and equalization of the SN75LVPE5412 must be set such that the output signal swing at DC and high frequency does not exceed the DC and AC linearity ranges of the devices, respectively.
| Pin ModeGAIN | I2C Modeflat_gain_2:0 | Flat Gain |
|---|---|---|
| L0 | 0 | ?5.6dB |
| L1 | 1 | ?3.8dB |
| L2 | 3 | ?1.2dB |
| L3 | 7 | +2.6dB |
| L4 (float) | 5 | +0.6dB (default recommendation) |
