Product details
Overview
LTM9008IY-14#PBF from Analog Devices (formerly Linear Technology) is a 14-bit, 65 Msps octal simultaneous-sampling analog-to-digital converter (ADC) with integrated serial LVDS outputs, 800 MHz full-power bandwidth sample-and-hold, and on-chip bypass capacitance. It delivers 73.7 dB SNR and 90 dB SFDR at 70 MHz input, operates from a single 1.8 V supply, and targets high-channel-count RF digitization in software-defined radios and cellular base stations.
For engineers reviewing the LTM9008IY-14#PBF datasheet, LTM9008IY-14#PBF pinout, LTM9008IY-14#PBF application, or LTM9008IY-14#PBF equivalent, this page provides verified specifications, thermal-grade packaging details (–40°C to +85°C), LVDS serialization modes (1-/2-lane), input range selection (1–2 VP-P), and validated alternative options for multichannel wideband data acquisition systems.
Technical Context
The LTM9008IY-14#PBF implements eight independent 14-bit ADC cores with synchronized sampling, each featuring a 800 MHz full-power bandwidth track-and-hold amplifier and internal reference buffer. Its architecture supports differential or single-ended encode clocking (ENC+/ENC–) with duty cycle stabilization, enabling full-speed performance across wide input duty cycles.
Digital output uses serialized LVDS: two bits per channel in 2-lane mode (65 Msps), or one bit per channel in 1-lane mode (reduced sample rates). The device integrates internal 0.1 µF bypass capacitors on VDD and OVDD, eliminating external bulk capacitance, and features SPI-configurable modes including shutdown and nap states for dynamic power management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit with no missing codes over temperature - guarantees monotonicity and full code coverage in precision measurement. |
| Sampling Rate | 65 Msps maximum - enables Nyquist sampling of signals up to 32.5 MHz or undersampling of IF signals up to 70 MHz. |
| SNR / SFDR | 73.7 dB SNR and 90 dB SFDR at 70 MHz input - supports high-fidelity digitization of demanding RF waveforms. |
| Power per Channel | 88 mW at 65 Msps (2-lane, 3.5 mA LVDS) - reduces thermal load in dense multichannel arrays. |
| Analog Input Range | Selectable 1 VP-P to 2 VP-P differential - simplifies front-end gain staging without external scaling. |

Pinout & Package
140-pin (11.25 mm × 9.00 mm × 2.72 mm) BGA package with flow-through pinout optimized for controlled-impedance LVDS routing and minimal board area. Internally bypassed VDD/OVDD pins eliminate need for external bulk capacitors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1+ / AIN1– to AIN8+ / AIN8– | Differential analog inputs (8 channels) | Accepts 1–2 VP-P differential signals; each pair referenced to dedicated VCM bias outputs (VCM14, VCM23, etc.). |

| OUT1A/OUT1B to OUT8A/OUT8B | LVDS serialized data outputs | Two differential pairs per channel in 2-lane mode; FR+/FR– frame sync aligns all 8-channel samples. |
| VDD / OVDD | Analog and output supply rails | 1.8 V supplies with integrated 0.1 µF ceramic bypass - eliminates external decoupling components. |
| CSA / CSB / SCK / SDI | SPI configuration interface | Allows per-group register control (CSA for Ch1/4/5/8; CSB for Ch2/3/6/7); supports mode, power, and output current setup. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LVDS serializer | Reduces interface lines by >75% vs parallel output - cuts PCB layer count and EMI in high-density RF boards. |
| On-chip bypass capacitance | 0.1 µF per VDD/OVDD rail - removes requirement for external bulk caps, saving 4–6 mm² per supply domain. |
| Flow-through BGA pinout | Input and output pins arranged on opposite sides - enables straight trace routing and minimizes crosstalk between analog and digital sections. |
| Configurable serialization mode | 1-lane (1-bit/ch) or 2-lane (2-bit/ch) LVDS - allows trade-off between data rate and FPGA I/O resource usage. |
| Internal clock duty cycle stabilizer | Maintains <±0.5% duty cycle tolerance - ensures consistent aperture jitter even with asymmetric clock sources. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9257BCPZ-65 | 14-bit, 65 Msps octal ADC with parallel CMOS outputs; requires external reference and decoupling; no integrated serializer. | Better suited for FPGA interfaces with abundant I/O but limited LVDS lanes; higher board-level component count and layout complexity. | Choose AD9257BCPZ-65 when system FPGA lacks LVDS receivers or requires lowest possible latency (no serialization pipeline). |
| LTM9007IY-14#PBF | Same family, 40 Msps max sampling rate; lower power (59 mW/channel); identical pinout and feature set except speed grade. | Valid drop-in replacement where 40 Msps meets system bandwidth requirements; reduces thermal load and power supply demand. | Choose LTM9007IY-14#PBF for cost-optimized or thermally constrained deployments where 40 Msps suffices (e.g., narrowband SDR, mid-tier medical imaging). |
Compared with LTM9008IY-14#PBF, AD9257BCPZ-65 trades integrated LVDS serialization for raw interface flexibility, while LTM9007IY-14#PBF offers identical architecture at reduced speed and power-enabling scalable design reuse across performance tiers without PCB redesign.

FAQ
What is the maximum sampling rate supported by the LTM9008IY-14#PBF?
The LTM9008IY-14#PBF supports a maximum sampling rate of 65 Msps in its highest speed grade. This is confirmed in the datasheet's Timing Characteristics table under fS (Sampling Frequency) for LTM9008-14, with guaranteed operation across the full –40°C to +85°C temperature range. At 65 Msps, it operates in 2-lane LVDS mode with 3.5 mA output current.
Does the LTM9008IY-14#PBF require external bypass capacitors?
No, the LTM9008IY-14#PBF does not require external bypass capacitors on VDD or OVDD. As stated in the Features and Pin Functions sections, it integrates internal 0.1 µF ceramic bypass capacitance on both supply rails. This eliminates the need for external bulk capacitors, reducing board space and component count while maintaining stable analog performance.
How many analog input channels does the LTM9008IY-14#PBF have, and what is their sampling behavior?
The LTM9008IY-14#PBF has eight fully differential analog input channels (AIN1+/- through AIN8+/-) with true simultaneous sampling. All eight channels acquire data at the exact same instant upon each encode clock edge, ensuring phase coherence critical for beamforming, MIMO, and multichannel spectral analysis. This is explicitly defined in the DESCRIPTION section and verified in the TYPICAL APPLICATION diagram.
What LVDS serialization modes does the LTM9008IY-14#PBF support, and how do they affect data throughput?
The LTM9008IY-14#PBF supports two LVDS serialization modes: 2-lane (two bits per channel per clock cycle) and 1-lane (one bit per channel per clock cycle). In 2-lane mode at 65 Msps, it outputs 130 Mbps per differential pair; in 1-lane mode, maximum sample rate drops to 40 Msps or 25 Msps depending on configuration. Mode selection is controlled via the CSA/CSB and SCK pins per the DIGITAL INPUTS AND OUTPUTS section.
What is the operating temperature range of the LTM9008IY-14#PBF, and how is it indicated in the part number?
The LTM9008IY-14#PBF is rated for operation from –40°C to +85°C. This industrial temperature grade is encoded in the part number by the "I" suffix in "LTM9008IY-14#PBF", as confirmed in the ORDER INFORMATION table where "LTM9008IY-14#PBF" maps to "–40°C to 85°C". The "Y" denotes the 140-pin BGA package, and "#PBF" indicates lead-free finish.
