Analog Devices Inc. AD9094BCPZ-1000

Overview

AD9094BCPZ-1000 from Analog Devices is an 8-bit, quad-channel, 1 GSPS analog-to-digital converter with JESD204B Subclass 0/1 serial output, 1.4 GHz full-power analog input bandwidth, and on-chip differential buffer. It delivers 48.6 dBFS SNR and 71 dBFS SFDR at 611 MHz input with 1.44 V_p-p input range, targeting high-speed digitization in LIDAR receivers and wideband instrumentation.

For engineers reviewing the AD9094BCPZ-1000 datasheet, AD9094BCPZ-1000 pinout, AD9094BCPZ-1000 application, or AD9094BCPZ-1000 equivalent, this page provides verified specifications, validated pin functions, confirmed JESD204B lane configuration options, thermal management guidance via the exposed pad, and real-world synchronization support using SYSREF± and SYNCINB±AB/CD inputs.

Technical Context

The AD9094BCPZ-1000 integrates four independent pipelined ADC cores, each with sample-and-hold and buffered differential inputs supporting 1.44–2.16 V_p-p programmable range and 1.4 GHz full-power bandwidth. It uses multistage error correction logic to ensure no missing codes and ±0.1 LSB DNL across −40°C to +105°C.

JESD204B digital interface supports up to two lanes per ADC pair (AB or CD), configurable for Subclass 0 or Subclass 1 operation with lane rates up to 15 Gbps. Deterministic latency is maintained via SYSREF±-driven LMFC alignment, and multichip sync is enabled through dedicated SYNCINB±AB and SYNCINB±CD pins with LVDS/LVPECL/CMOS compatibility.

FAQ

What is the maximum analog input frequency supported by the AD9094BCPZ-1000?

The AD9094BCPZ-1000 supports a full-power analog input bandwidth of 1.4 GHz, meaning it can accurately digitize signals up to that frequency without significant amplitude roll-off. This specification is measured under standard conditions (1 GSPS, 1.44 V_p-p input, −40°C to +105°C) and enables direct RF sampling in L-band and S-band applications. The device maintains 48.4 dBFS SNR even at 1391 MHz input, confirming usable performance across its rated bandwidth.

Does the AD9094BCPZ-1000 support JESD204B Subclass 1 deterministic latency?

Yes, the AD9094BCPZ-1000 fully supports JESD204B Subclass 1 operation, including SYSREF±-driven LMFC alignment and deterministic latency control. Its pipeline latency is fixed at 45 sample clock cycles, and multichip synchronization is achieved via dedicated SYNCINB±AB and SYNCINB±CD inputs. Subclass 1 mode is configured via SPI registers and requires proper SYSREF± timing relative to the device clock (tSU_SR = −44.8 ps, tH_SR = 64.4 ps).

How is the analog input common-mode voltage configured on the AD9094BCPZ-1000?

The AD9094BCPZ-1000 provides two dedicated common-mode bias outputs: VCM_AB (Pin 12) for channels A and B, and VCM_CD/VREF (Pin 43) for channels C and D. Pin 43 is multifunctional-it operates as an output when using the internal 0.5 V reference, or as an input when an external reference is applied. Both outputs are internally buffered and require no external components for standard operation with the default 1.44 V_p-p input range.

What power supply voltages does the AD9094BCPZ-1000 require?

The AD9094BCPZ-1000 requires seven distinct supply rails: AVDD1/AVDD1_SR (0.9 V), AVDD2 (1.8 V), AVDD3 (2.5 V), DVDD (0.9 V), DRVDD1 (0.9 V), DRVDD2 (1.8 V), and SPIVDD (1.8 V). Each rail powers isolated circuit blocks-including ADC cores, serializers, clock buffers, and SPI interface-to minimize cross-talk and maximize SNR. The exposed thermal pad must be connected to analog ground to serve as the reference for AVDDx, DVDD, and DRVDD supplies.

Can the AD9094BCPZ-1000 operate with a single-ended clock input?

No, the AD9094BCPZ-1000 requires a differential clock input on CLK+ and CLK− pins, compliant with LVDS or LVPECL standards. The clock inputs have 32 kΩ differential impedance and accept 600–1600 mV_p-p differential swing. Single-ended clock sources must be converted using a transformer or dedicated LVDS/LVPECL driver; direct single-ended connection is not supported and may degrade jitter performance or prevent lock.
