5 / 6 page 5 SY88903V Micrel, Inc. M9999-091406 hbwhelp@micrel.com or (408) 955-1690 Output Termination The SY88903V outputs must be terminated with a 50Ω load to V CC –2V (or Thevenin equivalent). Layout and PCB Design Since the SY88903V 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 VREF LOSLVL VCC Figure 3. LOSLVL Circut 50Ω 50Ω 0.1µF 0.1µF 0.1µF VREF DIN– DIN+ Figure 2. Differential Input Configuration The SY88903V 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: LOSLVS = VCC -1.32V + R1 + R2 ≥ 2.6kΩ R2 × 1.32V R1 + R2 |
