Product Overview
The AD9789BBCZ is a high-performance 14-bit RF DAC from Analog Devices, supporting up to 2.4 GSPS update rate for direct RF signal generation in communication systems. It integrates a 4-channel DUC, SRRC interpolation filters and multi-format QAM encoders, completing baseband channel combination and digital upconversion internally. It outputs RF signals covering the 1st, 2nd and 3rd Nyquist zones, eliminating phase imbalance and LO leakage defects of traditional analog modulation circuits. The 164-ball CSP_BGA package delivers stable thermal performance, low power consumption and high reliability for mass communication transmission equipment.
Core Advantages
Direct RF Synthesis Pipeline up to 2.4 GSPS
2.4 GSPS high-speed DAC core generates high-frequency RF signals directly, shifting analog filter frequencies and reducing peripheral component costs.
Integrated 4-Channel Digital Upconverter (DUC)
Independent modulation for four signal channels, greatly reducing FPGA computing resource overhead of upstream hardware.
Onboard Programmable QAM Encoding
Built-in hardware mapping for 16/32/64/128/256-QAM, simplifying signal processing for high-capacity data transmission.
Superb Spectral Purity & Dynamic Range
ADI optimized mixed-signal design provides excellent SFDR and ultra-low noise floor, distortion-free operation under multi-carrier dense signal conditions.

Frequently Asked Questions
Q1: Are AD9789BBCZ parts 100% original genuine?
A1: All AD9789BBCZ stock are brand-new original ADI chips. Every batch passes ESD cleanroom inspection, packed in original JEDEC trays with moisture-proof bags to protect BGA pins.
Q2: What benefits does direct RF DAC architecture bring?
A2: Traditional transmitters use analog quadrature mixers with drift, carrier leakage and alignment errors. AD9789 completes upconversion and QAM modulation digitally, outputting pure RF signals without analog calibration.
Q3: How does the built-in 4-channel DUC cut FPGA resource usage?
A3: Multi-carrier modulation needs complex filters and NCO logic which occupy massive FPGA resources. The on-chip hardwired DUC handles interpolation, filtering and mixing, greatly reducing FPGA logic consumption.
Q4: Any layout tips for 164-ball CSP-BGA package?
A4: 2.4 GSPS operation generates high heat, use multi-layer thermal vias connected to large ground copper planes for heat dissipation. Match differential LVDS trace impedance & length to eliminate signal skew.
Q5: Can I order samples of AD9789BBCZ for testing?
A5: Yes, we support sample orders for lab testing. Submit your sample demand via the inquiry form, we will quote and arrange shipment within 24 hours.
Q6: What is the minimum order quantity (MOQ) for this chip?
A6: MOQ is 1 piece, no bulk purchase requirements. Both small prototype orders and mass production orders are acceptable.
Q7: How long is the delivery time of AD9789BBCZ?
A7: In-stock items will be shipped within 1-2 working days. Global delivery normally takes 3-7 days by DHL/FedEx/UPS.
Q8: Can you provide datasheet and CAD library for AD9789BBCZ?
A8: Sure, original ADI datasheet, schematic symbols and PCB footprint files are available for free upon your request.
Q9: What payment methods do you support?
A9: We accept T/T Bank Transfer, PayPal, Credit Card and Western Union for global buyers.
