AD9228ABCPZ-65

Overview

The AD9228ABCPZ-65 is a quad, 12-bit analog-to-digital converter (ADC) operating at sampling rates up to 65 MSPS. It integrates four pipeline ADCs with on-chip sample-and-hold circuits in a single package. The device requires a single 1.8 V power supply and accepts LVPECL, CMOS, or LVDS-compatible clock signals. It features a 315 MHz full-power analog bandwidth and a 2 V p-p differential input voltage range. Digital outputs utilize Serial LVDS compliant with ANSI-644 standards. The component includes programmable clock and data alignment, flexible bit orientation, and built-in digital test pattern generation via an SPI interface.

Feature Summary

• Integrates four independent 12-bit ADC channels within a compact footprint for space-constrained designs.
• Provides low power consumption of 119 mW per channel at maximum sampling speed.
• Includes dedicated Data Clock Output (DCO) and Frame Clock Output (FCO) pins to simplify system synchronization.
• Supports individual channel power-down modes to minimize energy usage when specific channels are inactive.

Applications

• Medical imaging and nondestructive ultrasound systems
• Portable ultrasound and digital beam-forming equipment
• Quadrature radio receivers
• Diversity radio receivers
• Optical networking applications

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current documentation to confirm performance grade and packaging specifications. Ensure that the procurement source provides valid traceability for RoHS compliance status. Confirm that the delivered components match the specified industrial temperature range requirements for the intended deployment environment.

Selection Notes

Select this model when a design requires four synchronized high-speed conversion channels within a limited board area. Consider the AD9228ABCPZ-65 over other variants if the application demands a 65 MSPS sampling rate rather than the lower 40 MSPS option. Evaluate the pin-compatible family members, such as the AD9219 or AD9259, if different resolution requirements arise during the development phase.

Part Context

This component belongs to the Analog Devices AD9228 series of high-performance serial LVDS ADCs. It shares a pinout architecture with the AD9287, AD9219, and AD9259, facilitating potential upgrades or downgrades in resolution without redesigning the PCB layout. The device is designed to replace older multi-component solutions by consolidating multiple converters into a single integrated circuit.

Replacement Considerations

The AD9228ABCPZ-40 serves as a direct functional substitute offering identical pinouts and features but operates at a reduced 40 MSPS sampling rate. Designers requiring higher resolution should evaluate the AD9259, while those needing lower resolution may consider the AD9219 or AD9287 within the same pin-compatible family.
