In the event of a discrepancy in values between this guide and the Product Specification Document (PSD), the PSD takes precedence.
This chapter provides information related to the RF (Radio
Frequency) integration of the MC57xx and MC87xx modules
with host devices. The frequencies of operation and perfor‐
mance specifications vary depending on the module model
used. RF performance parameters for typical modules are
listed in Table 3‐1 and Table 3‐2.
Note: Values in this guide are taken from the appropriate product
specification documents (PSDs) (listed in
page 13) — in the case of a discrepancy between this document and
the relevant PSD, use the value listed in the PSD.
