Product details
Overview
LTC2192CUKG#TRPBF 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.
For engineers reviewing the LTC2192CUKG#TRPBF datasheet, LTC2192CUKG#TRPBF pinout, LTC2192CUKG#TRPBF application, or LTC2192CUKG#TRPBF equivalent, key selection criteria include its 550 MHz full-power bandwidth, serial LVDS output flexibility (1/2/4-lane), single 1.8 V supply operation, and ±2 LSB INL over temperature-critical for multi-channel data acquisition and portable medical imaging systems.
Technical Context
The LTC2192CUKG#TRPBF integrates two independent 16-bit ADC cores with shared clocking and reference circuitry, supporting true simultaneous sampling for coherent dual-channel acquisition. Its on-chip duty cycle stabilizer enables full-speed performance across wide encode clock duty cycles (2%–98%), while internal clock jitter reduction preserves SNR at high input frequencies.
Digital interface uses serialized LVDS outputs per channel with programmable lane count (1/2/4 bits per clock edge) and optional 100 Ω on-die termination. Configuration is managed via SPI-compatible serial port or parallel logic inputs, with dedicated pins for frame start (FR±) and data clock (DCO±) synchronization in multi-device systems.
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 signals up to 32.5 MHz or undersampling of IF bands up to 550 MHz. |
| SNR / SFDR | 77 dB SNR and 90 dB SFDR at 70 MHz input-meets stringent spectral purity requirements for communications receivers. |
| Aperture Jitter | 0.07 psRMS (differential encode)-directly enables high-fidelity undersampling of 100+ MHz IF signals without external jitter cleanup. |
| Power Consumption | 198 mW total at 65 Msps, 2-lane LVDS mode-enables thermally constrained designs in portable and dense PCB layouts. |
| Analog Supply | Single 1.8 V (1.7–1.9 V) rail-simplifies power delivery and reduces board-level noise coupling versus multi-rail ADCs. |
| Input Bandwidth | 550 MHz full-power bandwidth-preserves amplitude and phase integrity for wideband RF/IF inputs without external amplification. |
Pinout & Package
Package: 52-lead (7 mm × 8 mm) plastic QFN with exposed thermal pad (Pin 53 = GND). Requires soldering of exposed pad to PCB ground plane for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCM1 (1) | Channel 1 common-mode bias output | Nominally VDD/2; used to set AIN1± common-mode voltage-must be bypassed with 0.1 µF capacitor to GND. |

| FR±, DCO± (31–32, 35–36) | Frame start and data clock outputs | Synchronous timing references for downstream FPGA/ASIC capture-reduces setup/hold timing margin requirements. |
| PAR/SER (10) | Programming mode select | Ground = serial SPI interface (CS/SCK/SDI/SDO); VDD = parallel control (CS/SCK/SDI configure lane count/output current). |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous dual-channel sampling | Enables phase-coherent I/Q demodulation and time-of-flight measurements without inter-channel skew compensation. |
| Programmable LVDS serialization (1/2/4 lanes) | Reduces PCB trace count by up to 4× versus parallel interfaces-critical for high-density RF front-end layouts. |
| Internal clock duty cycle stabilizer | Eliminates need for external clock conditioning circuits when using asymmetric clocks (e.g., from PLLs or dividers). |
| Configurable input range (1–2 VP-P) | Allows optimization of dynamic range for varying signal amplitudes without external gain stages or attenuators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9680BCPZ-500 | 14-bit, 500 Msps, JESD204B interface, higher power (1.5 W), wider bandwidth (1.2 GHz) | Targets ultra-wideband radar and 5G massive MIMO-not suitable for low-power portable systems | Select when >250 Msps sampling or JESD204B backplane integration is required; avoid for 65 Msps cost/power-sensitive designs. |
| LTC2262CUK#TRPBF | 12-bit, 65 Msps, parallel CMOS outputs, lower SNR (70 dB), no internal reference | Designed for legacy FPGA interfaces with limited LVDS support and relaxed dynamic range needs | Choose only if system lacks LVDS-capable receivers or requires simpler timing (no FR/DCO signals); not drop-in compatible due to pinout and feature set differences. |
Compared with AD9680BCPZ-500 and LTC2262CUK#TRPBF, the LTC2192CUKG#TRPBF uniquely balances 16-bit resolution, 65 Msps speed, ultralow jitter, and sub-200 mW power in a serial LVDS QFN package-making it optimal for portable, battery-powered, or thermally constrained high-fidelity digitization where JESD204B complexity or 12-bit limitation is unacceptable.

FAQ
What is the maximum sampling rate supported by the LTC2192CUKG#TRPBF?
The LTC2192CUKG#TRPBF supports a maximum sampling rate of 65 Msps, as confirmed in the datasheet's "Timing Characteristics" table under fS parameter for the LTC2192 grade. This rate is achievable in all LVDS serialization modes (1/2/4-lane) when using the differential encode input and proper power supply decoupling. Operation above 65 Msps is not specified or guaranteed.
Does the LTC2192CUKG#TRPBF require an external reference voltage?
No-the LTC2192CUKG#TRPBF includes an internal 1.25 V reference (VREF pin) and supports three input range configurations via the SENSE pin: ±1 V (SENSE = VDD), ±0.5 V (SENSE = GND), or ±0.8·VSENSE (external 0.625–1.3 V applied to SENSE). An external reference is optional and only needed for higher accuracy or custom range requirements.
How many LVDS data lanes does the LTC2192CUKG#TRPBF support per channel?
The LTC2192CUKG#TRPBF supports 1, 2, or 4 serialized LVDS lanes per channel, configurable via the PAR/SER pin and CS/SCK logic levels. In 4-lane mode, each channel uses four differential pairs (e.g., OUT1A± through OUT1D±), reducing data rate per lane to 1/4 of the sample rate-simplifying FPGA capture timing and reducing EMI.
What is the operating temperature range for the LTC2192CUKG#TRPBF?
The LTC2192CUKG#TRPBF is rated for 0°C to 70°C ambient operation (C-grade), as indicated by the "CUKG" suffix in the part number and confirmed in the "Order Information" table. This distinguishes it from the I-grade variant (LTC2192IUKG#TRPBF), which operates from –40°C to +85°C.
Can the LTC2192CUKG#TRPBF be used with single-ended encode clock inputs?
Yes-the LTC2192CUKG#TRPBF supports single-ended encode operation by tying ENC– to GND and driving ENC+ with a TTL, CMOS, or PECL signal. The datasheet specifies VIH/VIL thresholds for ENC+ under this configuration (1.2 V/0.6 V at VDD = 1.8 V), and jitter performance remains within specification (0.09 psRMS typical) for single-ended use.
