Texas Instruments ADS5411IPJY

Overview

ADS5411IPJY from Texas Instruments is an 11-bit, 105 MSPS pipeline analog-to-digital converter (ADC) operating from a 5 V analog supply and delivering 3.3 V CMOS-compatible parallel outputs. It features 2.2 Vpp differential input range, 66.4 dBc SNR at 50 MHz IF, 90 dBc SFDR at 50 MHz IF, and integrated input buffer, track-and-hold, and reference circuitry. It targets high-performance digital receivers in base station infrastructure.

For engineers reviewing the ADS5411IPJY datasheet, ADS5411IPJY pinout, ADS5411IPJY application, or ADS5411IPJY equivalent, this page delivers verified electrical specs, thermal behavior, timing constraints, industrial temperature operation (−40°C to 85°C), and real-world interface guidance for RF sampling systems requiring low jitter and high spectral purity.

Technical Context

The ADS5411IPJY implements a monolithic bipolar pipeline architecture with dual-edge clocking-both rising and falling edges advance samples through internal stages-achieving 3-cycle latency and enabling 105 MSPS sustained conversion. Its on-chip analog input buffer isolates external signal sources from internal switching noise, while the internal 2.4 V reference and fixed 1 kΩ differential input impedance simplify front-end design.

It uses BiCom3 complementary bipolar process for optimized linearity and noise performance across wide input frequencies (up to 230 MHz), with specified AC performance including 65.7 dBc SNR and 81 dBc SFDR at 170 MHz IF. Digital outputs are two's complement format, driven by dedicated 3.3 V DRVDD supply independent of analog AVDD.

Key Specifications

Pinout & Package

FAQ

What is the maximum input frequency supported by the ADS5411IPJY?

The ADS5411IPJY specifies 570 MHz small-signal analog input bandwidth, enabling reliable digitization of RF signals up to at least 230 MHz while maintaining 65.4 dBc SNR and 71 dBc SFDR. This makes it suitable for undersampling applications in UHF bands, though system-level anti-alias filtering remains essential above Nyquist.

Does the ADS5411IPJY require an external reference voltage?

No, the ADS5411IPJY integrates a 2.4 V internal reference generator. Pins VREF, C1, and C2 must be bypassed to ground with 0.1 µF microwave capacitors, but no external reference IC or resistor network is needed-reducing component count and improving dc accuracy stability over temperature.

How is clock jitter managed in the ADS5411IPJY design?

The ADS5411IPJY minimizes jitter impact via dual-edge clocking and a low 150 fs aperture uncertainty (jitter). Its clock input accepts differential or single-ended drives, and internal 2.4 V common-mode bias allows flexible clock sourcing-while slew-rate-dependent jitter is reduced using high-amplitude (>3 Vpp) sinusoidal or PECL clocks per datasheet recommendations.

What does the OVR pin indicate on the ADS5411IPJY?

The OVR (Overrange) pin on the ADS5411IPJY outputs a logic-high signal whenever the differential analog input exceeds ±1.1 V-i.e., exceeds the 2.2 Vpp full-scale range. This real-time flag enables immediate gain adjustment or alarm triggering without requiring post-digitization analysis of the D0–D10 output bus.

Can the ADS5411IPJY operate with a non-50% clock duty cycle?

Yes-the ADS5411IPJY functions across 40% to 60% clock duty cycle per specifications, though optimal performance (especially SFDR) is achieved at 50%. The dual-edge pipeline architecture tolerates moderate duty cycle variation, but extreme deviations may increase aperture uncertainty and degrade harmonic performance at high input frequencies.
