LTC6900IS5 datasheet by Linear Technology

LTC6900IS5 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be achieved with the LTC6900IS5?
  The maximum clock frequency of the LTC6900IS5 is 2.5GHz, but it can be limited by the output load and the quality of the external clock source.
• How do I ensure the LTC6900IS5 is properly biased for optimal performance?
  To ensure proper biasing, connect the VCC pin to a 5V supply, and the VEE pin to a -5V supply or ground, depending on the application. Also, ensure that the input voltage range is within the recommended operating range of 2.7V to 5.5V.
• What is the recommended layout and routing for the LTC6900IS5 to minimize noise and jitter?
  To minimize noise and jitter, use a low-impedance, high-frequency layout with short traces and minimal vias. Keep the clock input traces away from noisy signals, and use a ground plane to reduce electromagnetic interference (EMI).
• How do I program the LTC6900IS5 for a specific frequency output?
  The LTC6900IS5 can be programmed using a 3-wire serial interface. Use the SDI (serial data input), SCK (serial clock), and SDO (serial data output) pins to set the desired frequency output. Refer to the datasheet for the programming protocol and frequency calculation formulas.
• What is the typical power consumption of the LTC6900IS5?
  The typical power consumption of the LTC6900IS5 is around 30mA, but it can vary depending on the output frequency, load, and operating conditions. Refer to the datasheet for more information on power consumption and thermal considerations.
