Frequently Asked Questions
Q1: What is the maximum clock frequency of AD9858BSVZ?
A: Internal clock up to 1 GSPS(1 GHz). External reference clock supports max 2 GHz via internal divide‑by‑2 circuit.
Q2: What peripherals are integrated inside AD9858BSVZ?
A: It integrates PFD, charge pump, programmable dividers and analog mixer, for hybrid DDS/PLL system design.
Q3: What is the operating supply voltage?
A: Main chip runs at 3.3V (3.14‑3.47V), no 1.8V core supply. Charge pump supports 5V input.
Q4: Difference between AD9858BSV and AD9858BSVZ?
A: AD9858BSV is tin‑lead version; suffix Z stands for RoHS lead‑free. Same die and pinout, pin‑to‑pin compatible.
Q5: What are alternative compatible DDS parts?
A: AD9854 is lower‑speed DDS alternative. AD9910 is higher‑performance upgrade, but different package and power, cannot drop‑in replace directly, hardware modification required.
Q6: Must AD9858BSVZ use an external VCO?
A: No, it can work as standalone DDS. PFD and charge pump are only used for DDS+PLL loop with external VCO.
Q7: How to get datasheet, evaluation board info or bulk quotation?
A: Please submit request via Quick Inquiry form for datasheet, register docs, eval‑board information and volume price.
