Texas Instruments recommends a 4-layer PCB with a solid ground plane, and a separate power plane for the analog and digital supplies. Additionally, keep the analog and digital signal traces separate and avoid crossing them over each other.
The GC4116-PBZ requires a dual power supply, with VCC (analog) ranging from 2.7V to 3.6V and VDD (digital) ranging from 1.8V to 3.6V. Ensure that the power supplies are decoupled with 10uF and 0.1uF capacitors, respectively, and that the analog and digital grounds are connected at a single point.
The maximum clock frequency for the GC4116-PBZ is 100 MHz. However, the actual clock frequency may be limited by the specific application and the quality of the clock signal.
To minimize power consumption, configure the GC4116-PBZ to use the lowest possible clock frequency, disable unused features, and use the power-down mode when not in use. Additionally, consider using a lower voltage power supply and optimizing the PCB layout for minimal power loss.
Texas Instruments recommends using a series termination scheme with a 50Ω resistor for the output signals. This helps to reduce signal reflections and improve signal integrity.
