(1) For component specifications, refer to the applicable data sheets from the component respective
manufacturer.
(2) All part numbers are generic, and boards may be shipped with alternate sourced parts which are
functionally equivalent. If substitution of parts is required by Megatel, Megatel will make every attempt to
provide a functionally equivalent parts, and Megatel reserves the right to change any component on the
board (for example, if a component becomes obsolete, a second source part may be substituted).
(3) Your configuration, selected by the order model number, determines which parts are populated on a your
board. Some parts in this table are optional, and some are alternately sourced parts.
