Product details

Overview

LTC2241IUP-12#PBF from Analog Devices (formerly Linear Technology) is a 12-bit, 210Msps pipelined analog-to-digital converter optimized for high-frequency signal digitization in communications infrastructure. It delivers 65.5dB SNR, 78dB SFDR at 10MHz input, and ultralow 95fs_RMS aperture jitter-enabling high-fidelity IF undersampling in wireless base stations and cable head-end systems.

For engineers reviewing the LTC2241IUP-12#PBF datasheet, LTC2241IUP-12#PBF pinout, LTC2241IUP-12#PBF application, or LTC2241IUP-12#PBF equivalent, key selection criteria include its ±0.5V/±1V selectable input range, LVDS/CMOS/demux-CMOS output flexibility, 1.2GHz full-power bandwidth, –40°C to +85°C industrial temperature rating, and 64-pin 9mm × 9mm QFN package with exposed thermal pad.

Technical Context

The LTC2241IUP-12#PBF implements a five-stage CMOS pipelined ADC architecture with integrated correction logic and flexible reference programming via the SENSE pin. Its differential analog input path supports ±0.5V or ±1V ranges, while the dual-reference structure (REFHA/REFHB/REFLA/REFLB) enables precise common-mode control and noise rejection.

It features programmable output modes-including LVDS, full-rate CMOS, and two demultiplexed CMOS formats (interleaved or simultaneous update)-and includes an optional clock duty cycle stabilizer, shutdown/nap modes, and data-ready clock outputs (CLKOUTA/CLKOUTB). The ENC+/ENC– differential encode interface accepts PECL, LVDS, TTL, or CMOS clocks.

Key Specifications

Parameter	Value and Actual Design Meaning
Resolution	12-bit with guaranteed no missing codes over –40°C to +85°C-ensures monotonicity in closed-loop control and measurement systems.
Sampling Rate	210Msps maximum-supports Nyquist sampling of signals up to 105MHz or undersampling of IF bands up to 1.2GHz full-power bandwidth.
SNR / SFDR	65.5dB SNR and 78dB SFDR at 10MHz input-meets dynamic range requirements for LTE/WiMAX receiver digitization and power amplifier linearization.
Aperture Jitter	95fs_RMS-limits sampling-time uncertainty to enable <66dB SNR at 200MHz input frequency per SNR_JITTER = –20log(2π·f_IN·t_JITTER).
Analog Supply	Single 2.5V VDD supply (2.375V–2.625V)-simplifies power delivery versus dual-supply ADCs and reduces board-level complexity.
Power Dissipation	585mW in CMOS mode, 805mW in LVDS mode-enables thermal management in dense RF front-end modules without forced air cooling.
Input Range	Selectable ±0.5V or ±1V differential full-scale range via SENSE pin-allows optimization for low-noise preamp stages or higher-voltage mixer outputs.

Pinout & Package

Package: 64-lead plastic QFN (9mm × 9mm), exposed thermal pad (Pin 65 = GND), RoHS-compliant lead-free finish. Requires soldering of exposed pad to PCB ground plane for thermal and electrical performance.

Pin/Terminal	Circuit Role	Design Meaning
AIN+, AIN– (Pins 1–4)	Differential analog input pair	Accepts wideband RF/IF signals up to 1.2GHz; requires matched 100Ω differential trace routing and proper termination.
ENC+, ENC– (Pins 17–18)	Differential encode clock inputs	Trigger sampling on edge transitions; support single-ended drive with bypass capacitor on ENC– for TTL/CMOS clocks.
LVDS (Pin 57)	Output mode selection	Configures LVDS (VDD), demux-CMOS interleaved (2/3VDD), demux-CMOS simultaneous (1/3VDD), or full-rate CMOS (GND).
MODE (Pin 58)	Output format & duty cycle control	Selects offset binary/2's complement output and enables/disables clock duty cycle stabilizer for jitter-sensitive applications.
SENSE (Pin 59)	Reference programming input	Sets input range: tied to VCM → ±0.5V; tied to VDD → ±1V; external voltage 0.5V–1V → ±V_SENSE.
VCM (Pin 60)	1.25V internal reference output	Provides common-mode bias for differential drivers and serves as SENSE reference for ±0.5V range configuration.
CLKOUTA / CLKOUTB (Pins 39, 38)	Data-valid strobes for A/B buses	In demux-CMOS mode, CLKOUTA latches DA0–DA11 on falling edge; CLKOUTB latches DB0–DB11 on rising (simultaneous) or falling (interleaved) edge.
GND (Pins 16, 61, 64, 65)	Power ground terminals	Multiple dedicated GND pins plus exposed thermal pad ensure low-impedance return paths for analog, digital, and output driver sections.

Key Features

Feature	Design Value
Ultralow 95fs_RMS aperture jitter	Enables high-SNR undersampling of 200MHz+ IF signals without external jitter-cleaning circuitry.
Three configurable output formats	LVDS (low EMI), full-rate CMOS (simplest interface), or demux-CMOS (reduced timing skew at half data rate).
Selectable ±0.5V/±1V input range	Matches varying signal chain gain profiles-e.g., ±0.5V for low-noise LNA outputs, ±1V for high-level mixer stages.
Integrated clock duty cycle stabilizer	Compensates for >30%–70% clock duty cycle variation, preserving sampling accuracy without external PLL conditioning.
Industrial temperature grade (–40°C to +85°C)	Validated operation across extended ambient conditions required for outdoor base stations and industrial test equipment.
Shutdown and nap power modes	Reduces power to 1mW (sleep) or 28mW (nap) during idle periods-critical for battery-backed or energy-constrained systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed ADC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AD9230-250EBZ	12-bit, 250Msps; higher sample rate but 63.5dB SNR (typ) and 72dB SFDR (typ) at 10MHz-lower dynamic range than LTC2241IUP-12#PBF.	Better suited for wider instantaneous bandwidth (>125MHz) where SNR >63dB is acceptable.	Choose AD9230-250EBZ when system requires >210Msps sampling and can trade 2dB SNR for increased Nyquist zone coverage.
LTC2242IUP-12#PBF	Pin-compatible 12-bit, 250Msps upgrade; identical architecture, package, and feature set-only difference is higher max sample rate and slightly higher power (920mW).	Direct drop-in replacement where 250Msps is needed and board layout supports additional 115mW dissipation.	Select LTC2242IUP-12#PBF when upgrading existing LTC2241IUP-12#PBF designs to higher sampling rates without changing PCB or firmware.

Compared with AD9230-250EBZ, the LTC2241IUP-12#PBF offers superior SNR/SFDR for demanding IF sampling, while LTC2242IUP-12#PBF provides a seamless 250Msps upgrade path with identical footprint, interface, and thermal profile-making it ideal for scalable platform design.

FAQ

What is the operating temperature range of the LTC2241IUP-12#PBF?

The LTC2241IUP-12#PBF is rated for industrial operation from –40°C to +85°C. This specification is validated across all key AC and DC parameters-including SNR, SFDR, INL, and DNL-and is explicitly defined in the Absolute Maximum Ratings and Converter Characteristics tables of the official datasheet. The "I" grade designation confirms this extended temperature capability.

Does the LTC2241IUP-12#PBF support both LVDS and CMOS output interfaces?

Yes, the LTC2241IUP-12#PBF supports three distinct output configurations via the LVDS pin (Pin 57): LVDS mode (LVDS = VDD), full-rate CMOS (LVDS = GND), and two demultiplexed CMOS modes (LVDS = 1/3VDD or 2/3VDD). Each mode uses separate output drivers and timing-LVDS outputs require 100Ω differential termination, while CMOS outputs allow adjustable OVDD from 0.5V to 2.625V.

How does the SENSE pin configure the input range on the LTC2241IUP-12#PBF?

The SENSE pin (Pin 59) directly programs the LTC2241IUP-12#PBF's full-scale differential input range: connecting SENSE to VCM selects ±0.5V, tying it to VDD selects ±1V, and applying an external voltage between 0.5V and 1V sets ±V_SENSE. This analog programming eliminates need for external gain-switching circuitry and maintains DC accuracy across all ranges.

What is the pipeline latency of the LTC2241IUP-12#PBF, and is it fixed?

The LTC2241IUP-12#PBF has a fixed 5-cycle pipeline latency in all output modes-meaning the digital output corresponding to a given analog sample appears 5 clock cycles after the sampling edge. This deterministic latency is critical for time-aligned DPD loops and synchronous multi-ADC systems, and is confirmed in the Timing Characteristics table under "Pipeline Latency."

Can the LTC2241IUP-12#PBF operate with a single 2.5V supply?

Yes, the LTC2241IUP-12#PBF operates from a single 2.5V analog supply (VDD = 2.375V to 2.625V) and supports independent output supply (OVDD) ranging from 0.5V to 2.625V. This single-supply architecture simplifies power design versus traditional dual-supply ADCs and is explicitly specified in the Power Requirements section of the datasheet.
