GTL2000DGG,112 datasheet by NXP Semiconductors

GTL2000DGG,112 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the signal traces short and away from the power planes. Use a 50-ohm impedance-controlled trace for the clock signal.
• How do I ensure signal integrity with the GTL2000DGG,112?
  Use a termination resistor (e.g., 50 ohms) at the receiver end, and ensure the transmission line is properly terminated. Also, use a clock signal with a rise time < 1 ns to minimize signal reflections.
• What is the maximum operating frequency for the GTL2000DGG,112?
  The maximum operating frequency is 1.5 GHz, but it depends on the specific application and PCB design. Consult the datasheet and application notes for more information.
• Can I use the GTL2000DGG,112 in a non-GTL application?
  Yes, but it's not recommended. The GTL2000DGG,112 is optimized for GTL (Gunning Transceiver Logic) applications. Using it in a non-GTL application may require additional components and can affect performance.
• How do I handle power sequencing and reset for the GTL2000DGG,112?
  Power up the device in the following sequence: VCC, VCCA, and then VCCIO. Ensure a clean power-up sequence and a reset signal (if required) to prevent latch-up or other issues.
