Layout and PCB Design Since the SY88943V is a high-frequency component, performance can be largely determined by the board layout and design. A common problem with high-gain amplifiers is the feedback from the large swing outputs to the input via the power supply. DESIGN PROCEDURE The SY88943V ground pin should be connected to the circuit board ground. Use multiple PCB vias close to the part to connect to ground. Avoid long, inductive runs which can degrade performance. R2 × 1.32V R1 + R2 NOTES: SD LVL = VCC -1.32V + R1 + R2 ≥ 2.6kΩ R1 R2 SDLVL VREF VCC Figure 3.
