6.3.1.4 Variable Gain Amplifier (VGA)

The DS280DF810 receiver implements a VGA. The VGA assists in the recovery of extremely small signals, working in conjunction with the CTLE to equalize and scale amplitude. The VGA has 1-bit control via Register 0x8E[0], and the VGA is enabled by default. In addition to the VGA, the CTLE implements its own gain control via register 0x13[5] to adjust the DC amplitude similar to the VGA. For more information on how to configure the VGA refer to the DS280DF810 Programming Guide.
