PGA Gain Registers
There are three PGA registers for individually programming the gain in the RED, GREEN, and BLUE channels.
Each gain register has 9 bits of resolution. Bits D[9:1] control the gain while bit D0 is N/A (don’t care).
The
XRD9818 has two gain ranges to help interface to imagers that have 3V or 2V of output signal swing. The GS
bit, located in the MODE 1 register, defaults to GS=0 for a gain of 1x to 5x or if GS=1 the gain would be 1.5x to
7.5x. The gain range of 1 to 5x (GS=0) is intended for use with imagers that have a 3V output swing, while the
gain range 1.5 to 7.5x is intended for imagers with 2V or less of output swing. The coding for the PGA registers
is straight binary. See “Section 4.3, Programmable Gain” on page 20 for a functional description of the
XRD9818’s gain stage.
