Texas Instruments ADC083000CIYB/NOPB

Overview

ADC083000CIYB/NOPB from Texas Instruments is an 8-bit, 3 GSPS high-performance CMOS analog-to-digital converter optimized for direct RF sampling applications. It achieves 7.0 ENOB at 748 MHz input with 3 GHz sampling, consumes 1.9 W typical at +1.9 V supply, and delivers 10⁻¹⁸ word error rate. It is used in digital oscilloscopes and satellite set-top boxes requiring ultra-wideband digitization.

For engineers reviewing the ADC083000CIYB/NOPB datasheet, ADC083000CIYB/NOPB pinout, ADC083000CIYB/NOPB application, or ADC083000CIYB/NOPB equivalent, key selection criteria include full-power bandwidth (3 GHz), LVDS output compatibility (IEEE 1596.3-1996), SDR/DDR clocking flexibility, on-chip self-calibration, and industrial temperature range support (−40°C to +85°C).

Technical Context

The ADC083000CIYB/NOPB employs a folding-and-interpolating architecture with fully differential comparators and a self-calibrating sample-and-hold amplifier to maintain dynamic performance up to Nyquist. Its dual-converter core samples on both edges of a 1.5 GHz differential clock to achieve 3 GSPS throughput.

It integrates a 1:4 demultiplexer routing data across four independent LVDS buses (Da–Dd), each operating at 750 MSPS, with pipeline latencies ranging from 13 to 14.5 input clock cycles. Output formatting is offset binary, and common-mode voltage is adjustable (0.8–1.15 V) for interface compatibility.

Key Specifications

Pinout & Package

The ADC083000CIYB/NOPB is housed in a thermally enhanced 128-lead exposed-pad HLQFP package. The exposed pad must be soldered to a ground plane to ensure rated thermal performance (θJ-PAD = 2.8°C/W) and electrical stability.

FAQ

What is the absolute maximum input clock frequency supported by the ADC083000CIYB/NOPB?

The ADC083000CIYB/NOPB supports a maximum differential input clock frequency of 1.5 GHz, enabling 3 GSPS sampling via dual-edge triggering. Exceeding this limit risks timing violation and degraded ENOB. The minimum clock frequency is 500 MHz, and duty cycle must be maintained between 20% and 80% for reliable operation. This specification is validated per the SNAS358N datasheet revision July 2009.

Does the ADC083000CIYB/NOPB support DC-coupled analog inputs?

Yes, the ADC083000CIYB/NOPB supports DC-coupled analog inputs using the VCMO pin to establish common-mode bias at VIN+ and VIN−. When DC-coupled, VCMO must be actively driven within 0.95–1.45 V and loaded ≤80 pF; it is grounded only for AC-coupled configurations. The analog input common-mode range is VCMO ±50 mV, and full-scale differential swing remains 600 or 820 mVP-P depending on FSR pin state.

How does the power-down mode affect calibration state in the ADC083000CIYB/NOPB?

The ADC083000CIYB/NOPB retains its factory and on-command calibration coefficients during power-down mode (PD = high), allowing wake-up conversion accuracy to be restored within 1 µs (tWU). No recalibration is required upon exit from power-down, preserving measurement consistency across intermittent operation. This behavior is confirmed in the "Power Down Mode" section of the SNAS358N datasheet.

What LVDS standard compliance does the ADC083000CIYB/NOPB meet?

The ADC083000CIYB/NOPB LVDS outputs comply with IEEE 1596.3-1996, including differential output voltage (470–920 mVP-P), common-mode range (0.8–1.15 V), and 100 Ω differential impedance. It deviates only in adjustable common-mode voltage-unlike fixed 1.2 V in standard LVDS-enabling interoperability with diverse FPGA I/O banks and custom receivers.

Can the ADC083000CIYB/NOPB be synchronized across multiple devices?

Yes, the ADC083000CIYB/NOPB supports multi-device synchronization via dedicated DCLK_RST+ and DCLK_RST− pins (pins 22/23) or a single-ended DCLK_RST (pin 15), selectable via Configuration Register bit 14. A positive differential pulse resets internal clock dividers and aligns DCLK phase across converters, enabling coherent sampling in phased-array or MIMO systems as documented in the "Multiple ADC Synchronization" section.
