Analog Devices Inc. AD9430BSVZ-170

Overview

AD9430BSVZ-170 from Analog Devices is a 12-bit, 170 MSPS analog-to-digital converter optimized for high dynamic performance in wideband communications systems. It features 700 MHz full-power analog bandwidth, on-chip track-and-hold and reference, 3.3 V single-supply operation, and dual-output modes (CMOS demultiplexed or LVDS interleaved). It targets broadband cable reverse path and radar subsystems requiring precise digitization of IF/RF signals.

For engineers reviewing the AD9430BSVZ-170 datasheet, AD9430BSVZ-170 pinout, AD9430BSVZ-170 application, or AD9430BSVZ-170 equivalent, this page delivers verified specifications, validated package mapping, confirmed CMOS/LVDS output configurations, industrial-temperature operation (–40°C to +85°C), and real-world timing and linearity data directly traceable to Rev. E datasheet testing conditions.

Technical Context

The AD9430BSVZ-170 implements a 12-bit pipeline ADC core with integrated scalable reference and clock duty cycle stabilizer. Its analog front end supports differential input ranges of 1.536 V_pp (S5 = GND) or 0.766 V_pp (S5 = AVDD), and it accepts LVPECL-level encode clocks via CLK+/CLK− inputs.

Digital interface flexibility includes two independent CMOS output ports (DA0–DA11 and DB0–DB11) operating at 105 MSPS each in demultiplexed mode, or a single LVDS port delivering interleaved 12-bit data at full 170 MSPS. Latency is fixed at 14 cycles in LVDS mode and 14/15 cycles in parallel CMOS mode.

Key Specifications

Pinout & Package

AD9430BSVZ-170 is housed in a 100-lead e-PAD TQFP (exposed heat slug), surface-mount plastic package rated for –40°C to +85°C operation. The conductive slug must be soldered to a solid ground plane to maintain junction temperature within specification under full-load conditions.

FAQ

What is the maximum analog input frequency supported by the AD9430BSVZ-170?

The AD9430BSVZ-170 has a full-power analog bandwidth of 700 MHz, meaning it maintains specified dynamic performance (e.g., SNR ≥ 65 dB) for input frequencies up to 700 MHz. This enables undersampling architectures for RF/IF digitization in L-band radar and broadband communications, provided the Nyquist criterion is satisfied relative to the 170 MSPS sampling rate.

Does the AD9430BSVZ-170 require an external reference voltage?

No, the AD9430BSVZ-170 includes an on-chip 1.235 V reference and supports internal reference mode by floating the SENSE pin. External reference operation is optional and requires driving VREF with a 1.23 V source while tying SENSE to DRVDD - but internal mode is fully functional and eliminates external component cost.

How does the AD9430BSVZ-170 handle clock input jitter?

The AD9430BSVZ-170 specifies 0.25 ps rms aperture uncertainty (jitter), directly limiting SNR at high input frequencies. Its integrated clock duty cycle stabilizer mitigates encode clock asymmetry, and the LVPECL-compatible CLK+/CLK− inputs accept differential signals with <2 ns pulse width - ensuring robust timing margin against jitter-induced sampling error.

Can the AD9430BSVZ-170 operate in both CMOS and LVDS output modes simultaneously?

No, the AD9430BSVZ-170 operates exclusively in one output mode at a time, selected by the S2 pin: low for dual-port CMOS (DA/DB buses), high for LVDS (D0+ to D11+/- pairs). CMOS and LVDS drivers are mutually exclusive; simultaneous activation is not supported and may cause undefined behavior or damage.

What is the purpose of the OR_A and OR_B pins on the AD9430BSVZ-170?

The OR_A and OR_B pins are active-high out-of-range indicators tied to the A and B CMOS output ports respectively. They assert when the analog input exceeds the selected full-scale range (1.536 V_pp or 0.766 V_pp), enabling real-time saturation detection for automatic gain control (AGC) or signal clipping mitigation in receiver chains using the AD9430BSVZ-170.
