Product details
Overview
LTM9011CY-14#PBF from Analog Devices is a 14-bit, 125Msps octal simultaneous-sampling ADC in a 140-pin BGA package, designed for high-dynamic-range RF digitization. It delivers 73.1dB SNR, 88dB SFDR, and 800MHz full-power bandwidth with serial LVDS outputs, internal bypassing, and 1.8V single-supply operation - deployed in cellular base stations and software-defined radios.
For engineers reviewing the LTM9011CY-14#PBF datasheet, LTM9011CY-14#PBF pinout, LTM9011CY-14#PBF application, or LTM9011CY-14#PBF equivalent, this page provides verified specifications, validated BGA pin mapping, real-world use cases in multichannel SDR front-ends, and confirmed alternative parts for sampling rate and temperature grade trade-offs.
Technical Context
The LTM9011CY-14#PBF integrates eight independent 14-bit ADC cores with synchronized sample-and-hold circuits, enabling true simultaneous sampling across all channels. Its architecture includes an internal clock duty cycle stabilizer, selectable 1- or 2-lane LVDS serialization, and programmable input ranges (1–2VP-P) - supporting wideband IF sampling without external clock conditioning.
It features integrated VCM bias generators (VCM14, VCM23, VCM58, VCM67), on-chip 100Ω LVDS termination, and SPI-configurable modes including shutdown and nap states. DC performance is characterized by ±1.2LSB INL (typ), ±0.3LSB DNL (typ), and 1.2LSBRMS transition noise over 0°C to 70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit with no missing codes - guarantees monotonicity and full code coverage for precision measurement systems. |
| Sampling Rate | 125Msps - enables Nyquist-limited digitization of signals up to 62.5MHz, suitable for LTE/5G IF sampling. |
| SNR / SFDR | 73.1dB SNR and 88dB SFDR at 70MHz input - ensures high-fidelity capture of weak signals amid strong interferers. |
| Input Bandwidth | 800MHz full-power bandwidth - supports direct sampling of UHF bands without external amplification or filtering. |
| Power per Channel | 140mW at 125Msps in 2-lane LVDS mode - reduces thermal load in dense multichannel arrays like phased-array receivers. |
| Supply Voltage | Single 1.8V analog (VDD) and 1.8V output (OVDD) - simplifies power delivery and eliminates level-shifting requirements. |
| Operating Temp | 0°C to 70°C - qualified for commercial-grade base station and portable medical imaging equipment. |
Pinout & Package
140-pin (11.25mm × 9mm × 2.72mm) BGA package with flow-through pinout optimized for signal integrity and minimal board area. Internally bypassed VDD/OVDD pins eliminate external decoupling capacitors; dedicated VCM outputs simplify differential input biasing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1+ / AIN1– | Channel 1 differential analog input | Accepts 1–2VP-P differential signal; common-mode biased via VCM14 - enables transformer-coupled RF inputs. |
| ENC+ / ENC– | Differential encode clock input | Triggers conversion on both edges; supports sine wave, LVDS, PECL, TTL, or CMOS drive - eliminates need for external clock buffers. |
| OUT1A / OUT1B | LVDS data output pair (Ch1) | Serial 2-bit LVDS output in 2-lane mode; 100Ω on-chip termination - reduces PCB routing complexity and stub length. |
| VCM14 / VCM23 / VCM58 / VCM67 | Common-mode bias outputs | Nominally VDD/2 (0.9V); internally bypassed - eliminates external bias networks for 8-channel differential input staging. |
| CSA / CSB | Serial chip select inputs | Enable independent configuration of channel groups (1/4/5/8 vs 2/3/6/7) - allows per-group gain/offset calibration in multichannel systems. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bypass capacitance | 0.1µF ceramic caps on VDD/OVDD/VCM pins - removes 8–12 external decoupling components per device, saving >15mm² PCB area. |
| Flow-through BGA pinout | Linear I/O arrangement from analog inputs to LVDS outputs - minimizes trace crosstalk and enables straight-layer routing in 4-layer layouts. |
| Selectable serialization mode | 1-lane (1-bit/ch) or 2-lane (2-bit/ch) LVDS - trades interface width for timing margin: 2-lane supports 125Msps; 1-lane eases FPGA capture at lower rates. |
| Internal clock duty cycle stabilizer | Compensates for 20%–80% input clock duty cycles - permits use of low-jitter but asymmetric clocks (e.g., from PLLs without duty-cycle correction). |
| Shutdown and nap modes | 2mW sleep power and 170mW nap power - enables dynamic power scaling in burst-mode receivers without reinitialization latency. |

FAQ
What is the maximum input frequency supported by the LTM9011CY-14#PBF?
The LTM9011CY-14#PBF has an 800MHz full-power bandwidth, meaning it can accurately digitize analog inputs up to 800MHz without significant amplitude roll-off. This enables direct sampling of UHF signals (e.g., 700–900MHz cellular bands) when paired with appropriate front-end filtering and impedance matching - a capability confirmed in the device's Figure 6 test circuit and typical performance plots.
Does the LTM9011CY-14#PBF require external decoupling capacitors?
No, the LTM9011CY-14#PBF does not require external decoupling capacitors on VDD, OVDD, or VCM pins - all are internally bypassed with 0.1µF ceramic capacitors. This integration reduces bill-of-materials count, saves PCB area, and improves high-frequency power integrity, as explicitly stated in the Features section and Pin Functions table.
How many LVDS data lanes does the LTM9011CY-14#PBF support, and what are the trade-offs?
The LTM9011CY-14#PBF supports two LVDS serialization modes: 2-lane (2 bits per channel) for full 125Msps operation, and 1-lane (1 bit per channel) for lower sampling rates. The 2-lane mode delivers maximum throughput with tighter timing margins; the 1-lane mode halves FPGA I/O usage and relaxes setup/hold timing - both modes are configurable via SPI or parallel pins (CS/SDI/SCK).
What is the guaranteed integral nonlinearity (INL) specification for the LTM9011CY-14#PBF over temperature?
The LTM9011CY-14#PBF guarantees ±1.2LSB typical INL over its full operating temperature range of 0°C to 70°C, with a maximum of ±4.1LSB. This is specified in the Converter Characteristics table under "Integral Linearity Error" with the "l" notation indicating full-temperature-range validity - critical for high-accuracy measurement and calibration-critical applications.
Can the LTM9011CY-14#PBF interface directly with an FPGA using LVDS I/O standards?
Yes, the LTM9011CY-14#PBF outputs LVDS signals compliant with ANSI TIA/EIA-644-A, featuring 100Ω on-chip termination, 247–454mV differential output voltage, and 1.125–1.375V common-mode voltage - all compatible with standard FPGA LVDS receivers (e.g., Xilinx SelectIO, Intel FPGA I/O). No external termination or level-shifting is required.
