• The RF Multiplexer is a block that inputs into the RF SUM AMP the I/V signals which are output differently
according to each pickup, in order to get the RF AUM signal. The RFSUM generates RF signals by
compensating according to the I/V polarity using the ADDRESS 00H's BUF_SEL. The RF MUX's operation is
selected by ADDRESS 00H's RFSUM_SEL REGISTER, and the RF MUX output value for each RFSUM_SEL
are as follows.
→ RFSUM_SEL (D3): Inputs and selects RFSUUM AMP's operation mode by Address 00H's (D5). (ABCD MUX &
RFSUM)
