4 / 6 page 4 SY88923V Micrel, Inc. M9999-051706 hbwhelp@micrel.com or (408) 955-1690 Output Termination The SY88923V outputs must be terminated with a 50 Ω load to V CC – 2V (or Thevenin equivalent). Layout and PCB Design Since the SY88923V is a high-frequency component, performance can largely be determined by board layout and design. A common problem with high-gain amplifiers is feedback from the large swing outputs to the input via the power supply. DESIGN PROCEDURE R1 R2 VCC LOSLVL VREF Figure 3. LOS LVL Circuit 50 Ω 50 Ω 0.1 µF 0.1 µF 0.1 µF DIN+ DIN– VREF Figure 2. Differential Input Configuration The SY88923V 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. Notes: LOS LVL = VCC -1.32V + R1 + R2 ≥ 2.6kΩ R2 × 1.32V R1 + R2 |
