Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital traces separate. The datasheet provides a recommended layout and routing guide.
Use a high-quality, low-ESR capacitor (e.g., 10uF) for decoupling, and ensure the power supply is clean and stable. TI recommends a 10nF capacitor between VCC and GND for additional filtering.
The TRS3232CDR supports clock frequencies up to 100 MHz, but the maximum frequency may vary depending on the specific application and PCB layout.
The TRS3232CDR has a built-in thermal shutdown feature that activates when the junction temperature exceeds 150°C. To handle this, ensure proper heat sinking, and consider using a thermal monitoring circuit to detect and respond to thermal shutdown events.
The recommended input impedance for the TRS3232CDR is 50 ohms, but this may vary depending on the specific application and signal source.
