AD9848KSTRL

Overview

The AD9848KSTRL is a specialized CCD signal processor manufactured by Analog Devices Inc. It integrates an analog front end with a 10-bit, 20 MHz A/D converter and a programmable timing driver. Key internal blocks include a Correlated Double Sampler (CDS), a Pixel Gain Amplifier (PxGA) with -2 dB to +10 dB range, and a Variable Gain Amplifier (VGA) providing 2 dB to 36 dB gain. The device features a black level clamp and outputs digital data via D0–D9 pins. It operates on multiple supply voltages: AVDD at 2.7 V to 3.6 V, DVDD1/2 at 2.7 V to 3.6 V for H-drivers, and DVDD3/4 at 3.0 V for logic. Power consumption is 220 mW at 20 MHz with 3 V supplies and 100 pF loading.

Feature Summary

• Integrated 10-bit, 20 MHz A/D Converter
• On-Chip Precision Timing Core with 1 ns resolution
• Programmable PxGA (-2 dB to +10 dB) and VGA (2 dB to 36 dB)
• Complete On-Chip Timing Driver for RG and H1–H4

Applications

• Digital Still Cameras

Procurement Notes

Verify the specific ordering suffix KSTRL against official documentation to confirm package type and temperature rating. Confirm RoHS compliance status as required by local regulations. Ensure ESD precautions are observed during handling due to device sensitivity.

Selection Notes

Select this model for applications requiring a 10-bit resolution and 20 MHz pixel rate. Choose the AD9849 variant if 12-bit resolution or 30 MHz speed is needed. Verify that the system supports the required 3-wire serial interface configuration for register programming.

Part Context

This component belongs to the AD9848/AD9849 family of CCD signal processors. It shares architectural similarities with the AD9849 but differs in ADC resolution and maximum clock frequency. Both devices utilize the same 48-lead LQFP package and serve similar image processing roles.

Replacement Considerations

The AD9849AKSTZRL is a functional alternative within the same family offering higher resolution and speed. Verify pin compatibility and register mapping before substitution.
