CXD3410GA

Detailed Description of Each Data

Shared data: D01 to D03 CTG [Category]

Of the data provided to the CXD3410GA by the CCD signal processor block serial interface, the CXD3410GA

loads D04 and subsequent data to each data register as shown in the table below according to the combination

of D01 to D03 .

PGA gain setting data: D06 to D15 GAIN [PGA gain]

The CXD3410GA can set the programmable gain amplifier (PGA) gain from –6dB to +42dB in 1024 steps by

using PGA gain setting data D06 to D15 GAIN.

The PGA gain setting data is expressed as shown in the table below using D06 to D15 GAIN.

GAIN is expressed as 1C3h .

For example, when GAIN is set to "000h", "080h", "220h", "348h" and "3FFh", the respective PGA gain setting

values are –6dB, 0dB, +20dB, +34dB and +42dB.
