Recommendations
This chapter provides the information necessary to understand the various
interface requirements to interconnect with the VZM20Q, associated
software-configurable items for the respective interface and, more generally,
good practices for board design when considering the various interface types.
Table 3-1 describes the requirements for trace characteristics.
Important: Different signals require different special needs. Please consider
carefully the interfacing requirement of each relevant connection.
Table 3-1: Requirements Overview: Trace Characteristics
Trace Characteristics Description
Digital Generic digital trace if reasonable high impedance
Supply Broader trace routing based on the power needs of the load
50 Ohm Conventionally used for RF routing. Track must be retained to this impedance
Quiet Intention is to keep away from digital signals and as short as possible, possibly burying
the signal
Ground Shortest VZM20Q Ground to Host Ground possible, best possible lowest impedance
