ADC3244IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC3244IRGZ25 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates up to 125 MSPS with a single 1.8-V supply. The device features a serial LVDS interface and an internal phase-locked loop for bit clock generation. Key electrical specifications include a typical SNR of 73.0 dBFS at fIN = 70 MHz and an SFDR of 93 dBc. Power consumption reaches 325 mW at maximum sampling rate. The component operates within a temperature range of -40°C to +85°C and is housed in a 48-pin VQFN package.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel architecture with 14-bit resolution and 125 MSPS maximum sampling rate
• Serial LVDS interface reducing pin count and supporting high integration density
• Internal PLL multiplies the sampling clock to derive the serialized bit clock
• Flexible input clock buffer with divide-by-1, -2, or -4 options

Analog To Digital Converters (ADC) Applications

• Multi-carrier, multi-mode cellular base stations
• Radar and smart antenna arrays
• Software-defined radios (SDRs)
• Communications test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix 'RGZ25' against the manufacturer's current orderable addendum to confirm packaging type and availability status. Confirm that the specific revision level matches system requirements, as documentation indicates potential updates to register maps and timing parameters across revisions.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 14-bit resolution and 125 MSPS throughput are required. Ensure the system can accommodate the 325 mW power dissipation at full speed. Verify compatibility with the serial LVDS output format and check if the internal clock divider meets the system clock architecture needs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC324x family, which includes variants with different maximum sampling rates (25, 50, and 80 MSPS). The ADC3244 specifically denotes the 125 MSPS variant within this 14-bit pipeline ADC series. It shares pinout compatibility with the 12-bit ADC322x family.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed direct substitutes include other members of the ADC324x family such as the ADC3243 for lower speed applications. For JESD204B interface requirements, the ADC32J44 is a functional alternative within the same performance class.
