C data sheet and evaluation board documentation.

Technical Context

The AD9695-1300EBZ implements the AD9695-1300 IC in a fully populated, calibrated evaluation platform featuring differential clock and analog input interfaces, four JESD204B lanes (up to 16 Gbps), and SPI-controlled configuration of DDCs, NCOs, decimation filters, and fast detect thresholds. It supports deterministic latency operation via SYSREF± and SYNCINB± for multichip synchronization in phased-array and MIMO systems.

Board-level design includes matched 50 Ω single-ended and differential signal paths, precision power delivery across 0.95 V/1.8 V/2.5 V rails, on-board temperature monitoring, and configurable GPIOs (FD_A/GPIO_A0, FD_B/GPIO_B0) for AGC integration. The board operates over −40°C to +105°C junction temperature, matching the IC's industrial-grade specification.

FAQ

What is the primary function of the AD9695-1300EBZ?

The AD9695-1300EBZ is an evaluation board designed to demonstrate and validate the performance of the AD9695-1300 dual 14-bit 1300 MSPS ADC. It provides complete signal chain access-including differential analog inputs, LVDS/LVPECL clock and SYSREF interfaces, JESD204B serial outputs, and SPI control-enabling rapid prototyping of wideband receiver systems without custom PCB development. The board ships with reference firmware and software tools for immediate characterization.

Does the AD9695-1300EBZ support both 1300 MSPS and 625 MSPS operation modes?

Yes, the AD9695-1300EBZ supports both speed grades via configuration. While optimized for the AD9695-1300 (1300 MSPS), the board's hardware and firmware allow reconfiguration to operate the AD9695 IC at 625 MSPS using SPI register settings and clock divider adjustments. Performance metrics such as SNR (67.3 dBFS typical at 172 MHz) and power consumption (0.98 W) shift accordingly, as specified in the AD9695 Rev. C data sheet Tables 2 and 3.

How does the AD9695-1300EBZ implement multichip synchronization?

The AD9695-1300EBZ implements multichip synchronization through dedicated SYSREF± and SYNCINB± differential inputs compliant with JESD204B Subclass 1. These pins accept externally generated alignment pulses to align the local multi-frame clock (LMFC) across multiple AD9695 devices, enabling deterministic latency and phase-coherent sampling in phased-array radar or massive MIMO systems. Board layout follows strict length-matching guidelines for these critical timing nets.

What are the power supply requirements for the AD9695-1300EBZ?

The AD9695-1300EBZ requires seven independent, low-noise DC supplies: 0.95 V (AVDD1, DVDD, DRVDD1), 1.8 V (AVDD2, DRVDD2, SPIVDD), and 2.5 V (AVDD3). Each rail must deliver specified current (e.g., AVDD2: 450–500 mA typical) with tight voltage regulation (±2%) and sub-10 mV ripple. The board includes test points and filtering networks to support validation using bench supplies or compatible power modules.

Can the AD9695-1300EBZ be used for DOCSIS 3.0 CMTS upstream receive path development?

Yes - the AD9695-1300EBZ is directly applicable to DOCSIS 3.0 CMTS upstream receive path development. Its 2 GHz analog input bandwidth, 1300 MSPS sampling rate, and >95 dB channel isolation meet the spectral occupancy and dynamic range requirements for multi-channel upstream burst reception (5–85 MHz). Integrated DDCs enable real-time channel selection and decimation, while JESD204B output simplifies interface to Xilinx or Intel FPGAs used in CMTS line cards.
