Product Overview
The AD9859YSVZ‑REEL7 is an integrated DDS chip from Analog Devices, supporting 400 MSPS internal clock and 10‑bit high‑speed DAC. It generates agile sine‑wave output up to 200 MHz, equipped with 32‑bit frequency tuning word, 14‑bit phase offset and built‑in 4x‑20x reference clock multiplier. Packaged in 48‑Lead TQFP‑EP (7×7mm) on 7‑inch tape‑and‑reel, it fits test‑measurement, wireless infrastructure and portable signal generator applications.
Core Advantages
High‑Speed & Fine Resolution
400 MSPS clock, 32‑bit FTW and 14‑bit phase offset, delivers sub‑Hertz frequency tuning and precise phase adjustment.
Low‑Power Design
Low power consumption under 1.8V core supply, suitable for battery‑powered and thermally‑sensitive devices.
Built‑in Clock Multiplier PLL
4x‑20x PLL multiplier allows high‑speed internal operation with low‑frequency external crystal, simplifying clock peripheral circuit.
Flexible SPI Control Interface
3‑wire / 4‑wire SPI compatible port, fast register update with minimal MCU pin resources.

Frequently Asked Questions
Q1: What is the maximum core clock rate of the AD9859YSVZ‑REEL7?
A: Maximum internal clock is 400 MSPS, supports output frequency up to 200 MHz for high‑precision signal synthesis.
Q2: What is the difference between AD9859YSV, AD9859YSVZ and AD9859YSVZ‑REEL7?
A: AD9859YSV: lead‑containing, tray package; AD9859YSVZ: RoHS lead‑free, tray package; AD9859YSVZ‑REEL7: RoHS lead‑free, 7‑inch tape‑and‑reel. Same die and pinout, fully pin‑to‑pin compatible.
Q3: What does “-REEL7” suffix mean?
A: It refers to 7‑inch tape‑and‑reel packaging, suitable for automatic SMT mass production.
Q4: Does AD9859YSVZ‑REEL7 need dual power supplies?
A: Yes, 1.8V for core and 3.3V for I/O are required for normal operation.
Q5: Are there pin‑to‑pin drop‑in alternatives for AD9859?
A: No direct pin‑compatible replacement. AD9858 / AD9912 are function‑similar alternatives, but PCB redesign is mandatory.
Q6: What is the package requirement for AD9859YSVZ‑REEL7?
A: 48‑Lead TQFP‑EP (7×7mm). The exposed thermal pad must connect to GND for reliable heat dissipation.
Q7: Can AD9859YSVZ(tray) replace AD9859YSVZ‑REEL7?
A: Yes, fully interchangeable. Only packaging differs, chip electrical performance is identical.
Q8: Where to get datasheet, sample and bulk quotation?
A: Submit your demand via Quick Inquiry form for datasheet, sample and volume pricing support.
