RF6001
Part of the POLARIS™ TOTAL RADIO™ Solution
Due to the filters added to the D/A converter outputs, the group delay and channel bandwidths will be slightly modified. The
plot below shows the amplitude response of the 80kHz channel bandwidth in 100kHz VLIF mode for the cascade of the
RF2716/2722 and RF6001 with and without the D/A converter filter.
The plot below shows the group delay response of the cascade of the RF2716/2722 and the RF6001 with and without the D/A
converter filter.
As a second example, the same two plots are repeated for a channel bandwidth of 120kHz in DCR mode.
RX Digital Mode (S_MODE=1)
If S_MODE is set true, the receiver baseband interface is configured to digital mode. In this mode:
ENR acts as the SSI bus enable pin.
CLKR acts as the clock output for the serial data transfer.
FSR acts as the frame sync output for the serial data transfer.
DRI and DRQ are the serial data outputs.
The following sections describe the various operational modes available.
