Product details
Overview
AD9683BCPZ-170 from Analog Devices is a 14-bit, 170 MSPS analog-to-digital converter with JESD204B Subclass 0/1 serial interface, 70.6 dBFS SNR at 185 MHz input, 88 dBc SFDR, and 1.8 V single-supply operation. It supports IF sampling up to 400 MHz and integrates a duty cycle stabilizer, on-chip voltage reference, and flexible 1.4–2.0 Vp-p analog input range. It targets high-performance communications receivers requiring compact, low-power digitization of wideband RF signals.
For engineers reviewing the AD9683BCPZ-170 datasheet, AD9683BCPZ-170 pinout, AD9683BCPZ-170 application, or AD9683BCPZ-170 equivalent, key selection criteria include JESD204B lane rate (3.4 Gbps), pipeline latency (36 ADC cycles), fast detect output latency (7 cycles), CML differential outputs, and support for both CLK± and RFCLK clocking options in industrial temperature range.
Technical Context
The AD9683BCPZ-170 implements a multistage differential pipelined ADC architecture with integrated error correction logic and a configurable integer 1-to-8 input clock divider. Its analog front end supports differential inputs up to 400 MHz with programmable common-mode bias via VCM output and internal termination.
JESD204B serial interface operates in Subclass 0 or Subclass 1 mode with SYSREF± and SYNCINB± synchronization inputs; CML output drivers deliver serialized 14-bit data at 3.4 Gbps lane rate. The device includes a dedicated fast detect (FD) output with 7-cycle latency and supports independent power-down of ADC core and serializer.

FAQ
What is the maximum analog input frequency supported by the AD9683BCPZ-170?
The AD9683BCPZ-170 supports intermediate frequency (IF) sampling up to 400 MHz, as specified in its full-power bandwidth of 1000 MHz and verified performance data showing usable SNR and SFDR at 305.1 MHz input. This enables direct digitization of L-band and S-band IF signals without downconversion, preserving signal integrity in radar and communications receivers.
Does the AD9683BCPZ-170 require an external voltage reference?
No, the AD9683BCPZ-170 integrates an internal analog-to-digital converter voltage reference, eliminating the need for an external reference IC. This simplifies board layout, reduces component count, and improves temperature stability-key advantages for compact, high-density RF front-end designs using the AD9683BCPZ-170.
What clocking options does the AD9683BCPZ-170 support?
The AD9683BCPZ-170 supports two clocking architectures: differential CLK± inputs (40–625 MHz, CMOS/LVDS/LVPECL compatible) and single-ended RFCLK input (500–1500 MHz). The RFCLK path bypasses the internal clock divider, offering lower jitter for demanding sampling applications where phase noise directly impacts SNR.
How does the fast detect (FD) output function on the AD9683BCPZ-170?
The FD pin on the AD9683BCPZ-170 is a CMOS-level output that asserts within 7 ADC conversion cycles when the analog input exceeds a user-programmable overrange threshold. This hardware-accelerated feature enables real-time automatic gain control (AGC) or signal clipping detection without processor intervention, critical for burst-mode communications and radar pulse detection.
Is the AD9683BCPZ-170 pin-compatible with other members of the AD968x family?
Yes, the AD9683BCPZ-170 shares the same 32-lead LFCSP package and pinout with AD9683BCPZ-250 and AD9684BCPZ-250, enabling drop-in replacement for speed grade upgrades. All variants maintain identical power, ground, analog input, clock, and JESD204B signal assignments-simplifying design reuse and platform scalability across the AD9683BCPZ-170 family.
