Product details
Overview
LTC2262CUJ-14#PBF from Analog Devices (formerly Linear Technology) is a 14-bit, 150Msps ultralow-power analog-to-digital converter optimized for high-frequency signal digitization in communications infrastructure. It delivers 72.8dB SNR and 88dB SFDR at 70MHz input, operates from a single 1.8V supply, and supports CMOS/DDR-CMOS/DDR-LVDS outputs - enabling direct interface with FPGAs in cellular base stations and software-defined radios.
For engineers reviewing the LTC2262CUJ-14#PBF datasheet, LTC2262CUJ-14#PBF pinout, LTC2262CUJ-14#PBF application, or LTC2262CUJ-14#PBF equivalent, key selection criteria include its 800MHz full-power bandwidth, 0.17psRMS aperture jitter, ±1LSB INL, 40-pin QFN package with exposed thermal pad, and SPI-configurable output modes for system-level noise and layout optimization.
Technical Context
The LTC2262CUJ-14#PBF employs a pipelined ADC architecture with on-chip correction logic to achieve 14-bit resolution without missing codes over temperature. Its sample-and-hold stage features 800MHz full-power bandwidth and 0.17psRMS jitter, enabling undersampling of IF signals up to 140MHz while maintaining 72.5dB SNR.
Digital interface flexibility is implemented via three selectable output modes: full-rate CMOS (14 parallel outputs), DDR-CMOS (7 pins, double-data-rate), or DDR-LVDS (7 differential pairs). Configuration is performed through a 4-wire SPI port supporting readback, with dedicated pins (PAR/SER, CS, SCK, SDI) enabling both serial and simplified parallel programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit with no missing codes over 0°C to 70°C - guarantees monotonicity and full dynamic range utilization in precision acquisition. |
| Sampling Rate | 150Msps maximum - supports real-time digitization of wideband signals up to Nyquist (75MHz) or IF undersampling (e.g., 68–69MHz dual-tone). |
| SNR / SFDR | 72.8dB SNR and 88dB SFDR at 30/70MHz - enables high-fidelity RF signal capture in SDR and medical imaging front ends. |
| Power Consumption | 149mW typical at 150Msps with CMOS outputs - reduces thermal load and simplifies power delivery in dense PCB layouts. |
| Analog Input Range | Selectable 1VP-P to 2VP-P differential - configurable via SENSE pin for optimal dynamic range matching to front-end amplifiers or transformers. |
| Aperture Jitter | 0.17psRMS - limits sampling uncertainty, preserving ENOB >12.1 bits even at 140MHz input frequency. |
| Full-Power Bandwidth | 800MHz - supports wideband analog input conditioning without external anti-aliasing filter roll-off penalties. |
Pinout & Package
Package: 40-lead (6mm × 6mm) plastic QFN with exposed thermal pad (Pin 41 = GND), rated for 0°C to 70°C operation. Requires soldering of exposed pad to PCB ground plane for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN+, AIN– | Differential analog input | Accepts 1–2VP-P differential signal centered at VCM (≈0.9V); 800MHz bandwidth enables direct RF sampling. |
| ENC+, ENC– | Differential encode clock input | Triggers conversion on rising/falling edges; supports sine, LVDS, PECL, TTL, or CMOS drive; duty cycle stabilizer optional. |
| VDD (Pins 9, 10, 40) | Analog supply | Single 1.8V supply (1.7–1.9V) powers core ADC and reference; bypassing with 0.1µF ceramics required per pin. |
| OVDD (Pin 26) | Digital output supply | Configurable 1.2–1.9V supply sets CMOS output swing or enables LVDS current mode (1.75mA/3.5mA). |
| D0–D13 / D0_1–D12_13 / D0_1±–D12_13± | Data outputs | Configurable as 14 single-ended CMOS, 7 DDR-CMOS, or 7 DDR-LVDS pairs - reduces pin count and EMI vs full-rate CMOS. |
| CLKOUT+, CLKOUT– | Output clock | Source-synchronous clock aligned to data edges; phase programmable via SPI to compensate for board trace delays. |
| CS, SCK, SDI, SDO | SPI configuration interface | 4-wire serial port for runtime mode control (output format, randomizer, nap/shutdown); SDO is open-drain with 2kΩ pull-up. |
| SENSE (Pin 39) | Reference programming | Selects input range: tied to VDD → ±1V; grounded → ±0.5V; 0.625–1.3V external → ±0.8×VSENSE. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow-jitter sampling | 0.17psRMS aperture jitter enables clean undersampling of 140MHz IF signals without degradation in SFDR or SNR. |
| Multi-mode digital outputs | Hardware-selectable CMOS / DDR-CMOS / DDR-LVDS interfaces reduce FPGA I/O count by 50% and lower system EMI. |
| Programmable input range | 1–2VP-P differential range selected via SENSE pin voltage, allowing precise matching to RF amplifier or transformer output levels. |
| Low-power sleep/napping | 0.5mW sleep mode and 9mW nap mode enable rapid power-state transitions in battery-powered or thermally constrained systems. |
| On-chip clock duty cycle stabilizer | Compensates for non-50% clock duty cycles without external circuitry, maintaining timing margin across process/voltage/temperature. |
| Integrated 1.25V reference | Internal reference with ±25ppm/°C drift and 1.250V ±25mV accuracy eliminates need for external reference in cost-sensitive designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9246BCPZ-150 | 14-bit, 150Msps; 74.5dB SNR, 90dB SFDR; 3.3V/1.8V dual supply; JESD204B interface only. | Requires FPGA with JESD204B support; higher power (340mW); no CMOS/DDR-CMOS fallback. | Choose AD9246BCPZ-150 when JESD204B serialization is needed and higher SFDR justifies added complexity and power. |
| ADS5463IPFP | 13-bit, 500Msps; 65.3dB SNR, 78dB SFDR; 3.3V/1.5V supplies; LVDS-only outputs; larger 80-pin HTQFP. | Higher speed but lower resolution; no SPI configuration; fixed 2VPP input range; no internal reference. | Choose ADS5463IPFP only when >200Msps sampling is mandatory and 13-bit ENOB suffices for the signal chain. |
Compared with AD9246BCPZ-150 and ADS5463IPFP, the LTC2262CUJ-14#PBF offers superior SNR efficiency (72.8dB at 149mW), flexible output interface options, integrated reference, and SPI configurability - making it optimal for cost- and power-constrained 150Msps applications where 14-bit fidelity is essential.

FAQ
What is the operating temperature range for the LTC2262CUJ-14#PBF?
The LTC2262CUJ-14#PBF is specified for commercial temperature operation from 0°C to 70°C. This grade is indicated by the "C" suffix in the part number and validated across all key parameters including SNR, SFDR, INL, and power consumption within that range.
Does the LTC2262CUJ-14#PBF require an external reference voltage?
No, the LTC2262CUJ-14#PBF includes an internal 1.25V reference with ±25ppm/°C drift and 1.250V ±25mV accuracy. An external reference can be applied via the SENSE pin (0.625–1.3V) to set custom input ranges, but it is not required for standard operation.
How is the digital output format configured on the LTC2262CUJ-14#PBF?
The LTC2262CUJ-14#PBF supports three output formats: full-rate CMOS, DDR-CMOS, and DDR-LVDS. Selection is made via hardware pins (SCK, PAR/SER) in parallel mode or through SPI register writes in serial mode - enabling runtime reconfiguration without changing PCB layout.
What is the purpose of the SENSE pin on the LTC2262CUJ-14#PBF?
The SENSE pin on the LTC2262CUJ-14#PBF configures the analog input range: tied to VDD selects ±1V, grounded selects ±0.5V, and an external 0.625–1.3V voltage selects ±0.8×VSENSE. This allows precise matching to front-end driver output swing without external gain adjustment.
Can the LTC2262CUJ-14#PBF operate with a single-ended encode clock?
Yes, the LTC2262CUJ-14#PBF supports single-ended encode clock operation: tie ENC– to GND and drive ENC+ with a 1.8V square wave. This reduces power consumption versus differential mode but maintains full 150Msps performance and timing specifications.
