Cautions for Handling Application Board
• For the achiev ement of high perf ormances in the MIX system, the 50ohm-matching is necessary in the
MIXIN port.
• Please place external elements connected to the RF line, near the pins.
(Especially , resisters of TXOUT, TXE, and RXE)
• The VCC/TXVCC/RXVCC decoupling capacitances are important f or the achiev ement of high perf ormances.
Please place these elements near the pins.
• In this diagram, coef f icients of the X'tal oscillation circuit are merely examples.
Please ask X'tal unit v endor about the best v alues of customer's specif ication.
