AD9957BSVZ-REEL

The AD9957BSVZ-REEL is Analog Devices’ AD9957 Direct Digital Synthesizer (DDS) in the BSVZ package, delivered on tape-and-reel (REEL) for automated assembly. It combines a DDS core with high‑resolution DACs to generate programmable RF signals from a reference clock. Control is via an SPI‑style serial interface, and users can set frequency, phase, and amplitude and switch channels rapidly. The BSVZ suffix denotes the specific package code, while REEL indicates reel packaging.
Key points:
- DDS-based RF signal generator with programmable frequency, phase, and amplitude.
- Integrated DACs and output drivers; controlled over SPI.
- Requires an external reference clock; suitable for rapid frequency switching and multi-tone/Signal generation applications.
- Packaging note: BSVZ = package variant; REEL = tape-and-reel packaging for automation.
For exact specs (frequency range, update rate, DAC resolution, power, jitter, spurs), consult the AD9957 datasheet and the product page.

Here are the key features of the AD9957BSVZ-REEL (DDS device in Tape & Reel packaging):
- Direct Digital Synthesizer (DDS) with high-resolution 14-bit DACs
- Four independent, phase-coherent output channels
- Wide frequency generation range with fractional-N-like tuning via phase accumulators
- On-chip clocking options: support for an external reference; integrated PLL/an optional clock multiplier
- Programmable control via SPI: frequency, phase, amplitude, waveform shape, and ramping
- Flexible modulation: I/Q/quadrature outputs and envelope/AM modulation
- Output options: differential/current-mode DAC outputs with external filtering/conditioning
- Low phase noise and high spurious-free dynamic range (SFDR across bands)
- Power: typical industrial range with robust power supply options
- Temperature range suitable for industrial use
- Packaging: Tape & Reel (BSVZ) for automated assembly
Note: For exact electrical specs (bandwidth, SFDR numbers, update rate, and pinout), refer to the AD9957 datasheet and the packaging/REEL specifications from Analog Devices.
