Product details
Overview
LTC2192CUKG#PBF from Analog Devices (formerly Linear Technology) is a dual-channel, simultaneous-sampling 16-bit analog-to-digital converter optimized for high-frequency, wide-dynamic-range signal digitization at 65 Msps. It delivers 77 dB SNR, 90 dB SFDR, and ultralow 0.07 psRMS aperture jitter-enabling undersampling of IF signals in cellular base stations and software-defined radios. Its serial LVDS outputs, single 1.8 V supply, and 52-pin QFN package support compact, low-power RF data acquisition systems.
For engineers reviewing the LTC2192CUKG#PBF datasheet, LTC2192CUKG#PBF pinout, LTC2192CUKG#PBF application, or LTC2192CUKG#PBF equivalent, key selection criteria include its 65 Msps sampling rate with 77 dB SNR at 70 MHz input, dual-channel simultaneity, LVDS serialization flexibility (1/2/4-lane), and C-grade temperature range (0°C to 70°C) in a 7 mm × 8 mm QFN.
Technical Context
The LTC2192CUKG#PBF integrates two independent 16-bit ADC cores with a shared 550 MHz full-power bandwidth sample-and-hold amplifier and internal clock duty cycle stabilizer. Its architecture supports differential or single-ended encode inputs (ENC+/ENC–), programmable input ranges (1–2 VP-P), and configurable LVDS output current (1.75 mA or 3.5 mA per lane).
Digital interface includes an SPI port for configuration and three operational modes (normal, nap, shutdown), with pipeline latency fixed at 7 cycles. The device uses internal reference (1.25 V ±25 ppm/°C) or external reference via SENSE pin, and features matched gain (±0.3%FS) and offset (±1.5 mV) between channels for coherent dual-channel processing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit with no missing codes over temperature-ensures monotonicity and full dynamic range utilization in precision measurement. |
| Sampling Rate | 65 Msps maximum-supports Nyquist sampling of up to 32.5 MHz baseband or undersampling of IF signals up to 140 MHz. |
| SNR / SFDR | 77 dB SNR and 90 dB SFDR at 70 MHz input-enables high-fidelity digitization of narrowband RF signals with minimal noise floor elevation. |
| Aperture Jitter | 0.07 psRMS-critical for maintaining ENOB >14.5 bits when undersampling multi-MHz IF carriers. |
| Power Consumption | 198 mW total at 65 Msps (2-lane, 3.5 mA mode)-enables thermally constrained designs in portable medical imaging and multi-channel DAQ systems. |

Pinout & Package
Package: 52-lead plastic QFN (7 mm × 8 mm), exposed pad (Pin 53) soldered to PCB ground for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCM1 (Pin 1) | Channel 1 common-mode bias output | Nominally VDD/2; used to bias AIN1+/AIN1– differential pair-requires 0.1 µF bypass to GND for stable CM level. |
| AIN1+, AIN1– (Pins 3, 4) | Channel 1 differential analog input | Accepts 1–2 VP-P differential signal; CM voltage set by VCM1-supports transformer-coupled or active balun interfaces. |
| ENC+, ENC– (Pins 17, 18) | Differential encode clock input | Starts conversion on rising/falling edges; internal duty cycle stabilizer enables robust timing with non-50% clocks. |

| FR+, FR– (Pins 31, 32) | Frame start differential output | Indicates start of new sample frame-synchronizes downstream FPGA or DSP capture logic across both channels. |
| DCO+, DCO– (Pins 35, 36) | Data clock differential output | Provides source-synchronous clock for LVDS data lanes-eliminates need for separate clock routing and skew management. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 16-bit, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9269BCPZ-65 | 65 Msps, 16-bit, dual-channel; requires 3.3 V AVDD + 1.8 V DVDD; no internal reference; 75 dB SNR at 70 MHz. | Higher supply complexity; lower SNR limits dynamic range in weak-signal detection; lacks integrated duty cycle stabilizer. | Select when external reference control and mixed-voltage design are acceptable, and SNR margin >2 dB is not required. |
| ADS52J90IRGCT | 65 Msps, 16-bit, quad-channel; 1.8 V only; 76.5 dB SNR at 70 MHz; JESD204B interface instead of LVDS. | Higher channel density but incompatible interface; JESD204B demands FPGA with SerDes PHY and link-layer IP; higher layout complexity. | Select for scalable multi-channel systems where JESD204B infrastructure already exists and quad-channel integration offsets interface overhead. |
Compared with AD9269BCPZ-65 and ADS52J90IRGCT, the LTC2192CUKG#PBF offers superior SNR (77 dB vs 75/76.5 dB), integrated 1.8 V operation, and LVDS simplicity-making it optimal for space-constrained, single-FPGA SDR and medical imaging platforms where analog performance and power efficiency are prioritized over channel count or interface standardization.

FAQ
What is the maximum sampling frequency supported by the LTC2192CUKG#PBF?
The LTC2192CUKG#PBF supports a maximum sampling frequency of 65 Msps, as confirmed in the datasheet's "Timing Characteristics" table under fS parameter for the LTC2192 grade. This rating assumes proper power supply decoupling, thermal management, and LVDS load compliance. Exceeding 65 Msps may violate timing margins and degrade SNR/SFDR performance.
Does the LTC2192CUKG#PBF require an external reference voltage?
No-the LTC2192CUKG#PBF includes an internal 1.25 V reference with ±25 ppm/°C drift, and supports external reference via the SENSE pin. When SENSE is tied to VDD, the device uses internal reference with ±1 V input range; grounding SENSE selects ±0.5 V range. An external 0.625–1.3 V reference applied to SENSE sets ±0.8×VSENSE input range.
How many LVDS data lanes does the LTC2192CUKG#PBF support, and how are they configured?
The LTC2192CUKG#PBF supports 1-, 2-, or 4-lane LVDS serialization per channel, selected via CS and SCK pins in parallel programming mode (PAR/SER = VDD) or SPI register writes in serial mode. In 4-lane mode, each channel outputs four bits per sample cycle on dedicated differential pairs (e.g., OUT1A–/OUT1A+, OUT1B–/OUT1B+, etc.).
What is the operating temperature range for the LTC2192CUKG#PBF?
The LTC2192CUKG#PBF is rated for the commercial temperature range of 0°C to 70°C, as indicated by the "C" suffix in the part number and confirmed in the "Order Information" and "Absolute Maximum Ratings" sections of the datasheet. This distinguishes it from the industrial-grade LTC2192IUKG#PBF (–40°C to 85°C).
Can the LTC2192CUKG#PBF operate with single-ended analog inputs?
No-the LTC2192CUKG#PBF is designed exclusively for differential analog inputs (AIN1+/AIN1– and AIN2+/AIN2–). Single-ended drive is not supported; attempting it degrades CMRR, increases noise, and violates the specified input common-mode voltage range (0.7–1.25 V). A balun or fully differential amplifier is required for single-ended source interfacing.
