Product details
Overview
AD9608BCPZRL7-105 from Analog Devices is a dual-channel, 10-bit, 105 MSPS analog-to-digital converter (ADC) operating from a single 1.8 V analog supply with 1.8 V CMOS or LVDS digital outputs. It delivers 61.7 dBFS SNR at 70 MHz input, 85 dBc SFDR, and features a 650 MHz analog input bandwidth, on-chip voltage reference, and differential input architecture. It is designed for IF sampling in communications receivers and portable ultrasound systems.
For engineers reviewing the AD9608BCPZRL7-105 datasheet, AD9608BCPZRL7-105 pinout, AD9608BCPZRL7-105 application, or AD9608BCPZRL7-105 equivalent, key selection considerations include its 105 MSPS conversion rate, dual-channel interleaving capability, programmable clock divider (1–8), DCO/data alignment control, and support for offset binary/Gray/twos complement output formats in both CMOS and LVDS modes.
Technical Context
The AD9608BCPZRL7-105 employs a multistage differential pipeline architecture with error correction logic to guarantee 10-bit accuracy and no missing codes across −40°C to +85°C. Its sample-and-hold circuit supports IF sampling up to 200 MHz while maintaining low power consumption of 95 mW per channel at full rate.
Dual independent ADC cores share a common differential clock input and support synchronized operation via SYNC pin. Digital outputs are configurable for parallel CMOS or LVDS (ANSI or reduced-swing), with optional data multiplexing and built-in deterministic/pseudorandom test pattern generation accessible via SPI interface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - guarantees monotonic transfer function and no missing codes over full temperature range. |
| Sampling Rate | 105 MSPS - maximum sustained conversion rate with DCS enabled; supports real-time digitization of wideband IF signals. |
| SNR @ 70 MHz | 61.7 dBFS - defines dynamic range usable for high-fidelity signal capture in diversity radio and I/Q demodulation. |
| SFDR @ 70 MHz | 85 dBc - indicates spurious-free performance critical for detecting weak signals adjacent to strong interferers. |
| Analog Input BW | 650 MHz - enables direct sampling of RF/IF signals up to 200 MHz without external anti-alias filtering. |
| Power Consumption | 95 mW/channel - enables battery-powered instrumentation and handheld medical devices with thermal constraints. |
| Digital Output Logic | 1.8 V CMOS or 1.8 V LVDS - provides interface flexibility with FPGAs and ASICs while minimizing EMI and power. |
| Input Voltage Range | 2 V p-p differential - matches standard transformer-coupled or balun-based front-end designs for RF receivers. |
Pinout & Package
AD9608BCPZRL7-105 is housed in a 64-lead, 9 mm × 9 mm RoHS-compliant LFCSP package with exposed thermal pad requiring solder connection to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+, CLK− | Differential clock input | Accepts CMOS/LVDS/LVPECL clocks; internal bias sets common-mode at 0.9 V; enables jitter-insensitive sampling with DCS option. |
| VIN+A, VIN−A / VIN+B, VIN−B | Differential analog inputs (Ch A/B) | 650 MHz bandwidth, 2 V p-p full-scale range, 7.5 kΩ differential impedance-optimized for transformer-coupled RF paths. |
| D0A–D9A, D0B–D9B | Parallel digital outputs | 10-bit CMOS or LVDS data bus per channel; LSB-to-MSB ordering; supports interleaved or independent channel readout. |
| DCOA, DCOB | Data clock outputs | Programmable phase-aligned clocks for latch timing; essential for reliable capture by FPGA input registers with adjustable skew. |
| PDWN, OEB | Power-down & output enable | Active-low controls: PDWN reduces power to 2.0 mW; OEB gates all digital outputs to prevent bus contention during idle states. |
| SPI pins (CSB, SCLK/DFS, SDIO/DCS) | Serial configuration interface | Enables runtime reconfiguration of output format, clock divider, test patterns, and DCO alignment without reset. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip voltage reference | 1.00 V ±2% output with 2 mV load regulation-eliminates need for external precision reference in space-constrained designs. |
| Programmable clock divider (1–8) | Allows use of higher-frequency, lower-jitter master clocks while maintaining precise 105 MSPS sampling-reduces clock synthesis complexity. |
| Integer latency of 16 cycles (CMOS) | Predictable, fixed pipeline delay simplifies timing closure in FPGA-based digital downconverters and real-time processing chains. |
| Built-in test pattern generation | Deterministic, pseudorandom, and user-defined patterns accessible via SPI-enables production testing and system-level validation without external signal sources. |
| Duty cycle stabilizer (DCS) | Compensates for >40% clock duty cycle variation while preserving SNR/SFDR-tolerates imperfect clock distribution networks. |
| Interleaved output mode | Multiplexes both channels onto shared 10-bit bus with alternating samples-halves I/O count and PCB routing density for compact form factors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 10-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9609BCPZ-125 | Single-channel, 125 MSPS, identical 10-bit resolution and 1.8 V supply but lacks second channel and interleaving capability. | Suitable for cost-sensitive single-path receivers where channel count is not required. | Select when board space or BOM count must be minimized and only one digitized path is needed. |
| AD9208BCPZ-500 | 14-bit, 500 MSPS, JESD204B serial output, wider bandwidth (3.5 GHz), significantly higher power (2.5 W total). | Targeted at high-end radar and wideband spectrum analyzers-not drop-in compatible due to interface, power, and layout requirements. | Choose only when higher ENOB (>12 bits) and >200 MHz instantaneous bandwidth are mandatory; requires FPGA with JESD204B support. |
Compared with AD9609BCPZ-125 and AD9208BCPZ-500, the AD9608BCPZRL7-105 uniquely balances dual-channel operation, 105 MSPS throughput, low power, and parallel CMOS/LVDS interfacing-making it optimal for portable, multi-antenna, and battery-constrained instrumentation where pin compatibility with legacy AD92xx family is also beneficial.

FAQ
What is the maximum analog input frequency supported by the AD9608BCPZRL7-105?
The AD9608BCPZRL7-105 supports analog input frequencies up to 200 MHz in IF sampling applications, enabled by its 650 MHz analog input bandwidth and patented sample-and-hold circuit. This allows direct digitization of intermediate frequency signals without downconversion, reducing system complexity and component count in radio receivers and ultrasound beamformers.
Does the AD9608BCPZRL7-105 support both CMOS and LVDS digital outputs simultaneously?
No-the AD9608BCPZRL7-105 supports either 1.8 V CMOS or 1.8 V LVDS digital outputs, selected at power-up via the SENSE pin configuration. Both modes are fully supported, but they cannot operate concurrently. LVDS mode offers lower power and EMI at high data rates, while CMOS simplifies interface with standard logic families.
What is the purpose of the RBIAS pin on the AD9608BCPZRL7-105?
The RBIAS pin on the AD9608BCPZRL7-105 connects to a 10 kΩ (1%) resistor to AGND to set the internal bias current for the on-chip voltage reference and sample-and-hold circuitry. Proper RBIAS termination is required for specified DC accuracy, gain error, and noise performance-omission or incorrect value degrades INL, DNL, and SNR.
Can the AD9608BCPZRL7-105 operate with an external voltage reference?
Yes-the AD9608BCPZRL7-105 supports external reference operation via the VREF pin. When an external 1.0 V reference is applied and SENSE is configured accordingly, the internal reference is disabled. This allows improved stability or temperature drift performance using a precision external source, though the internal 1.00 V ±2% reference is sufficient for most applications.
How does the SYNC pin function in the AD9608BCPZRL7-105?
The SYNC pin on the AD9608BCPZRL7-105 enables deterministic channel-to-channel synchronization in multi-device systems. A rising edge on SYNC aligns the sampling phases of both ADC cores and resets internal pipeline counters, ensuring sub-ns inter-channel skew for coherent signal processing in diversity receivers and phased-array ultrasound.
