Texas Instruments ADC07D1520CIYB/NOPB

Overview

ADC07D1520CIYB/NOPB from Texas Instruments is a dual-channel, 7-bit, low-power CMOS analog-to-digital converter capable of 1.5 GSPS per channel (or 3.0 GSPS in interleaved mode), delivering 6.8 ENOB at 748 MHz input with 10⁻¹⁸ code error rate, used in direct RF down-conversion and high-speed test instrumentation.

For engineers reviewing the ADC07D1520CIYB/NOPB datasheet, ADC07D1520CIYB/NOPB pinout, ADC07D1520CIYB/NOPB application, or ADC07D1520CIYB/NOPB equivalent, key selection considerations include LVDS output formatting (SDR/DDR), 1:2 demultiplexer mode support, interleave synchronization capability, and industrial-temperature operation with exposed-pad LQFP thermal management.

Technical Context

The ADC07D1520CIYB/NOPB employs a folding-and-interpolating architecture with fully differential comparators and a self-calibrating sample-and-hold amplifier to maintain flat dynamic performance beyond Nyquist. Its dual independent channels support non-demux (3.0 GSPS single-mode) or 1:2 demux (1.5 GSPS per bus) LVDS output routing.

It features dual differential clock inputs (CLK±), two sets of LVDS data outputs (DI/DQ and DId/DQd), programmable full-scale range via FSR pin or register, and extended control mode enabled by ECE pin for serial interface configuration - all operating from a single +1.9 V ±0.1 V supply with <1.9 W typical power in 1:2 demux mode.

Key Specifications

Pinout & Package

FAQ

What is the maximum input clock frequency supported by the ADC07D1520CIYB/NOPB?

The ADC07D1520CIYB/NOPB supports a maximum input clock frequency of 1.5 GHz in 1:2 demultiplexed mode. In non-demultiplexed mode, the maximum clock frequency is limited to 1 GHz per the datasheet specification. The device also supports minimum clock frequencies of 200 MHz (1:2 demux) and 500 MHz (DES mode), with duty cycle tolerance of 20–80%.

Does the ADC07D1520CIYB/NOPB support interleaved operation to achieve 3.0 GSPS?

Yes, the ADC07D1520CIYB/NOPB supports interleaved operation where its two internal 1.5 GSPS channels are synchronized to function as a single 3.0 GSPS analog-to-digital converter. This mode requires precise phase alignment of the input clocks and DCLK_RST signaling, and is explicitly documented in the datasheet as a supported configuration with defined pipeline latency and synchronization methodology.

What is the purpose of the CalRun pin on the ADC07D1520CIYB/NOPB?

CalRun is an open-drain output pin on the ADC07D1520CIYB/NOPB that asserts logic high during active self-calibration cycles - whether initiated by the CAL pin or via the Calibration register. It provides real-time visibility into calibration status for system-level timing coordination, allowing host controllers to pause data capture or defer configuration changes until calibration completes.

Can the ADC07D1520CIYB/NOPB operate with AC-coupled analog inputs?

Yes, the ADC07D1520CIYB/NOPB supports AC-coupled analog inputs. When using AC coupling, the VCMO pin must be grounded, and the full-scale differential input range is programmable between 650 mV_P-P and 940 mV_P-P via the FSR pin or Extended Control Mode registers. Input common-mode voltage is maintained internally, eliminating need for external bias networks.

What thermal management requirements apply to the ADC07D1520CIYB/NOPB package?

The ADC07D1520CIYB/NOPB uses a 128-pin exposed-pad LQFP package requiring the backside thermal pad to be soldered to a solid ground plane for rated thermal performance (θJC = 10°C/W). Without proper pad grounding, junction temperature rise exceeds specifications, degrading ENOB, SNR, and code error rate - especially critical given its 1.9 W typical power dissipation in active mode.
