ADC09SJ800AAVTQ1

Analog To Digital Converters (ADC) Overview

The ADC09SJ800AAVTQ1 is a single-channel, 9-bit analog-to-digital converter (ADC) operating at an 800 MSPS sampling rate. It features a non-interleaved architecture with a full-power input bandwidth of 6 GHz and supports direct RF sampling up to 4 GHz. The device utilizes a JESD204C serial interface supporting baud rates up to 17.16 Gbps with 64B/66B or 8B/10B encoding. Key performance metrics include a signal-to-noise ratio (SNR) of 53.5 dBFS and an effective number of bits (ENOB) of 8.51 bits at –1dBFS and 97 MHz. Power consumption is 840 mW at maximum speed, powered by 1.1 V and 1.9 V supplies.

Analog To Digital Converters (ADC) Feature Summary

• AEC-Q100 qualified for automotive applications across the –40°C to +125°C temperature range.
• Internal phase-locked loop (PLL) with integrated voltage-controlled oscillator (VCO) generates the sampling clock.
• JESD204C interface enables deterministic latency via Subclass-1 support and compatibility with JESD204B receivers.
• Four dedicated clock outputs simplify system clocking for FPGAs, ASICs, or adjacent ADCs.

Analog To Digital Converters (ADC) Applications

• Light detection and ranging (LiDAR)
• Frequency modulated continuous wave (FMCW) LiDAR systems
• Pulse-based LiDAR systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure that any additional characters in the part number do not alter the electrical characteristics or functional capabilities defined in the datasheet. Cross-reference the manufacturer's current product status to confirm availability and production lifecycle stage before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed data conversion solution is required for automotive environments. The 6 GHz bandwidth accommodates both FMCW and pulsed LiDAR architectures. Verify that the system can accommodate the 840 mW power dissipation and that the JESD204C lane configuration aligns with the target FPGA or ASIC transceiver capabilities.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC09xJ800-Q1 family, which includes quad (ADC09QJ800-Q1) and dual (ADC09DJ800-Q1) channel variants. All members share identical core specifications, including the 9-bit resolution, 800 MSPS rate, and 6 GHz bandwidth. The primary distinction lies in the number of analog input channels and the corresponding JESD204C lane requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the ADC09QJ800-Q1 and ADC09DJ800-Q1. These devices offer identical electrical performance but provide multiple channels instead of a single channel. System designers must account for the additional unused channels and adjust PCB layout and pin connections accordingly.
