AD9888KS-170

Specialized Overview

The AD9888KS-170 is a monolithic analog interface optimized for capturing RGB graphics signals from personal computers and workstations. It features an 8-bit resolution with a maximum conversion rate of 170 MSPS and a full-power analog bandwidth of 500 MHz, supporting resolutions up to 1600 × 1200 (UXGA) at 75 Hz. The device includes a triple ADC with an internal 1.25 V reference phase-locked loop (PLL) to generate a pixel clock from HSYNC and COAST inputs. Operating on a single 3.3 V power supply, it provides programmable gain, offset, and clamp controls via a 2-wire serial port. The component is housed in a 128-lead MQFP package and operates within a temperature range of 0°C to +70°C.

Specialized Feature Summary

• Integrates a 170 MHz triple ADC with an internal PLL for pixel clock generation from HSYNC and COAST signals.
• Provides full sync processing capabilities including composite sync and sync-on-green applications.
• Features a 2:1 analog input multiplexer and supports 4:2:2 output format modes.
• Includes midscale clamping and programmable gain, offset, and clamp controls accessible via a serial register.

Specialized Applications

• RGB graphics processing
• LCD monitors and projectors
• Plasma display panels

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required packaging and environmental standards. Confirm that the component meets all necessary regulatory compliance requirements for the intended deployment environment before finalizing procurement decisions.

Specialized Selection Notes

Select this model when a 170 MSPS sampling rate and 500 MHz analog bandwidth are required for high-resolution graphics capture. Ensure the design accommodates the 128-lead MQFP package dimensions and thermal characteristics. Verify that the system can provide the specified 3.3 V power supply and compatible digital logic levels for the serial control interface.

Specialized Part Context

The AD9888KS-170 belongs to the AD9888 series of analog flat panel interfaces manufactured by Analog Devices Inc. This series is designed to provide a complete solution for connecting standard PC graphics outputs to flat panel displays. The KS-170 variant specifically denotes the 170 MSPS performance tier within the family.

Specialized Replacement Considerations

Public confirmed substitute part numbers include AD9888KSZ-100 and AD9888KSZ-140. These variants share the same pinout and functional architecture but operate at lower maximum conversion rates of 100 MSPS and 140 MSPS respectively.
