9 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.

9.1 Application Information

This device is used for configurable frequency, programmable frequency, and timing division as shown in Typical Application.

9.2 Typical Application

9.2.1 Design Requirements

This device does not have balanced output drive. Take care to avoid bus contention because it can sink currents that would exceed maximum limits. The high drive will also create fast edges into light loads so routing and load conditions should be considered to prevent ringing.

9.2.2 Detailed Design Procedure

  1. Recommended Input Conditions:
  2. Recommended Output Conditions:
