Description
The HD49335NP/HNP is a CMOS IC that provides CDS-PGA analog processing (CDS/PGA) suitable for CCD camera
digital signal processing systems together with a 10-bit A/D converter and timing generator in a single chip.
There are address map and timing generator charts besides this specification. May be contacted to our sales department
if examining the details.
Functions
•
Correlated double sampling
•
PGA
•
Serial interface control
•
10-bit ADC
•
Timing generator
•
Operates using only the 3 V voltage
•
Corresponds to switching mode of power dissipation and operating frequency
Power dissipation: 220 mW (Typ), maximum frequency: 36 MHz (HD49335HNP)
Power dissipation: 150 mW (Typ), maximum frequency: 25 MHz (HD49335NP)
•
ADC direct input mode
•
QFN 64-pin package
Features
•
Suppresses low-frequency noise, which output from CCD by the correlated double sampling.
•
The S/H response frequency characteristics for the reference level can be adjusted using values of external parts and
registers.
•
High sensitivity is achieved due to the high S/N ratio and a wide dynamic range provided by a PG amplifier.
•
PGA, pulse timing, standby mode, etc., is achieved via a serial interface.
•
High precision is provided by a 10-bit-resolution A/D converter.
•
Difference encoded gray code can be selected as an A/D output code. It is effective in suppression of solarization
(wave pattern). It is patented by Renesas.
•
Timing generator generates the all of pulse which are needed for CCD driving.
