ICX224 SONY [Sony Corporation], ICX224 Datasheet - Page 45

• Manufacturer Part Number: ICX224
• Description: Timing Generator and Signal Processor for Frame Readout CCD Image Sensor
• Manufacturer: SONY [Sony Corporation]

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 .
Standby control data: D15 STB [Standby]
The operating mode of the CCD signal processor block is switched as follows. When the CCD signal processor
block is in standby mode, only the serial interface is valid.
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.
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.
