8 / 8 page LA1060 No.2650-8/8 Note for Application 1. Noise sensitivity setting When the LA1060 is used in conjunction with the LA2110, it is unnecessary to adjust the sensitivity. However, if any malfunction occurs, increase the noise sensitivity control VR form 0 Ω to 50kΩ—100kΩ to decrease the input noise level. 2. Gate time setting The recommended gate time is 120µs. If any malfunction occurs, shorten the gate time, and less malfunction will result. If the gate time is made longer, the multipath distortion detection sensitivity is increased. The gate time can be set by varying the value of the capacitor or resistor connected to pin 4. 3. Antenna holding function a. To hold the antenna at the weak input signal mode, set the value of the resistor connected to pin 6 to approximately 300k Ω. In this case, the pin 8 output is brought to High level. The antenna input level at which the antenna is held can be adjusted by varying the value (300k Ω) of the resistor. b. To switch the antenna even at the weak input signal mode, set the value of the resistor connected to pin 6 to approximately 10k Ω. 4. Forced antenna holding Set the pin 6 voltage to 2.5V or greater (example : connect to VCC through 10kΩ), and the antenna can be held on the pin 8 side, No products described or contained herein are intended for use in surgical implants, life-support systems, aerospace equipment, nuclear power control systems, vehicles, disaster/crime-prevention equipment and the like, the failure of which may directly or indirectly cause injury, death or property lose.
