10 Device Terminal Descriptions
10.1
The BlueCore4-ROM Plug-n-Go RF_IN terminal can be configured as either a single-ended or differential input. The
operational mode is determined by setting the PS Key PSKEY_TXRX_PIO_CONTROL (0x20).
10.1.1 RF Plug-n-Go
The 10 x 10mm 96-ball LFBGA package used on the BlueCore4-ROM Plug-n-Go device is an RF Plug-n-Go package,
where the terminal RF_CONNECT forms an unbalanced ouput with a nominal 50Ω impedance. This terminal can be
directly connected to an antenna requiring no impedance matching network as Figure 10.1 indicates.
