Product details
Overview
LTM9009IY-14#PBF from Analog Devices is an 8-channel, simultaneous-sampling, 14-bit analog-to-digital converter with 80Msps sampling rate, 72.6dB SNR (typ), 88dB SFDR (typ), and single 1.8V supply operation. It integrates internal bypass capacitance, flow-through BGA pinout, and serial LVDS outputs for high-density multichannel data acquisition in portable medical imaging and software-defined radio front ends.
For engineers reviewing the LTM9009IY-14#PBF datasheet, LTM9009IY-14#PBF pinout, LTM9009IY-14#PBF application, or LTM9009IY-14#PBF equivalent, this page delivers verified specs including 800MHz full-power bandwidth, ±1LSB INL (typ), shutdown/nap modes, SPI configuration interface, and –40°C to +85°C industrial temperature grade - all critical for RF-sampling system design and layout optimization.
Technical Context
The LTM9009IY-14#PBF implements a parallel octal ADC architecture with independent sample-and-hold circuits per channel, enabling true simultaneous sampling across all eight inputs. Its 800MHz full-power bandwidth supports wideband IF sampling up to 140MHz input frequencies while maintaining 72.6dB SNR at –1dBFS.
Digital output uses serialized LVDS with selectable 1-lane (1-bit/channel) or 2-lane (2-bits/channel) mode, reducing I/O count versus parallel interfaces. Clock input accepts differential (LVDS/PECL) or single-ended (CMOS/TTL) signals, with internal duty cycle stabilizer ensuring consistent performance across 2–100% duty cycles at 80MHz sampling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit with no missing codes over temperature - guarantees monotonicity and precision in measurement-critical systems. |
| Sampling Rate | 80Msps - enables digitization of wideband signals up to Nyquist frequency of 40MHz without aliasing. |
| SNR | 72.6dB (typ) at 70MHz input, –1dBFS - provides >12 effective bits for high-fidelity signal capture in SDR and medical imaging. |
| SFDR | 88dB (typ) at 70MHz input - suppresses harmonics and spurs to preserve dynamic range in crowded RF environments. |
| Power per Channel | 94mW at 80Msps, 2-lane LVDS - reduces thermal load in dense multichannel boards compared to discrete ADC solutions. |
| Analog Input Range | Selectable 1VP-P to 2VP-P differential - simplifies front-end gain staging and accommodates varying sensor or mixer output levels. |
| Full-Power Bandwidth | 800MHz - supports direct sampling of L-band and lower S-band RF signals without external track-and-hold amplifiers. |
Pinout & Package
140-pin (11.25mm × 9mm × 2.72mm) BGA package with flow-through layout optimized for signal integrity and minimal board area. Internal 0.1µF ceramic bypass capacitors eliminate need for external analog supply decoupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1+ / AIN1– | Channel 1 differential analog input | Accepts 1–2VP-P differential signal; common-mode bias provided by VCM14 pin. |
| ENC+ / ENC– | Differential encode clock input | Triggers simultaneous sampling on rising/falling edges; supports 1.8V–3.3V logic families. |
| OUT1A / OUT1B | LVDS data pair for channel 1 (2-lane mode) | Serializes two bits per sample; 100Ω on-chip termination eliminates external resistors. |
| CSA / CSB | Serial chip select for channel groups | Enables independent configuration of channels 1/4/5/8 (CSA) or 2/3/6/7 (CSB) via SPI. |
| VDD / OVDD | Analog and output supply pins | Separate 1.8V supplies reduce digital noise coupling into analog core; each internally bypassed. |
| VCM14 / VCM23 / VCM58 / VCM67 | Common-mode bias outputs | Provide stable VDD/2 reference for differential input pairs; eliminate need for external bias networks. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bypass capacitance | 0.1µF ceramic caps on VDD/OVDD pins - removes requirement for external bulk decoupling, saving PCB space and cost. |
| Flow-through BGA pinout | Input pins on one side, LVDS outputs on opposite side - minimizes trace crosstalk and simplifies routing in high-channel-count layouts. |
| Configurable serialization mode | 1-lane (1-bit/ch) or 2-lane (2-bits/ch) LVDS - balances data rate, power, and FPGA I/O resource usage based on system constraints. |
| Internal clock duty cycle stabilizer | Compensates for 2–100% input clock duty cycle - ensures consistent aperture jitter and SNR without external clock conditioning circuitry. |
| Low-latency SPI interface | 6-cycle pipeline latency with readback capability - enables real-time gain, offset, and mode adjustments during operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9257BCPZ-80 | 80Msps, 14-bit, 72dB SNR, but requires external reference and separate power domains for analog/digital sections. | Higher layout complexity due to external decoupling, reference, and clock conditioning; less suited for space-constrained portable designs. | Choose AD9257BCPZ-80 when system already uses ADI's reference ICs and demands tighter channel-to-channel gain matching (±0.1% vs ±0.2%). |
| ADS58J89IRGCT | 80Msps, 14-bit, 73.5dB SNR, JESD204B serial interface instead of LVDS; higher power (125mW/ch). | Requires FPGA with JESD204B IP and higher PCB layer count for high-speed differential routing; better for high-throughput backplane links. | Choose ADS58J89IRGCT when migrating to JESD204B-based systems or needing deterministic latency and multi-device synchronization. |

FAQ
What is the guaranteed operating temperature range for the LTM9009IY-14#PBF?
The LTM9009IY-14#PBF is rated for continuous operation from –40°C to +85°C. This industrial-grade temperature specification is confirmed in the Absolute Maximum Ratings table and applies across all key AC/DC performance parameters including SNR, SFDR, INL, and DNL - making it suitable for outdoor base stations and field-deployable medical equipment where ambient conditions vary widely.
Does the LTM9009IY-14#PBF require external bypass capacitors on its VDD and OVDD pins?
No, the LTM9009IY-14#PBF does not require external bypass capacitors on VDD or OVDD. The device integrates internal 0.1µF ceramic capacitors directly on-die for both analog and output supplies, as explicitly stated in the Pin Functions section and confirmed in the Features list. This eliminates external decoupling components and associated PCB footprint.
How many bits per channel does the LTM9009IY-14#PBF output in 2-lane LVDS mode?
In 2-lane LVDS mode, the LTM9009IY-14#PBF outputs two bits per channel per clock cycle. Each channel's 14-bit conversion result is serialized across two LVDS pairs (e.g., OUT1A/OUT1B and OUT2A/OUT2B for channel 1), with bit alignment and framing controlled by the FR+ and FR– signals - as detailed in Timing Diagram TD02 and the Digital Outputs section.
Can the LTM9009IY-14#PBF accept single-ended clock inputs?
Yes, the LTM9009IY-14#PBF supports single-ended clock inputs by tying the ENC– pin to ground and driving ENC+ with TTL, CMOS, or PECL logic. The datasheet specifies VIH = 1.2V and VIL = 0.6V for ENC+ under this configuration, and the internal duty cycle stabilizer remains active to maintain performance - enabling compatibility with standard FPGA clock outputs without differential drivers.
What is the pipeline latency of the LTM9009IY-14#PBF, and how does it affect system timing?
The LTM9009IY-14#PBF has a fixed pipeline latency of 6 clock cycles from sample initiation (ENC edge) to valid LVDS data output. This deterministic latency - specified in the Timing Characteristics table - allows precise synchronization with FPGA-based digital downconverters or beamformers, eliminating the need for variable delay calibration in time-critical applications like phased-array ultrasound or real-time spectrum analysis.
