From d0c162bc7a4ac82f6104506b17d7be05e1780336 Mon Sep 17 00:00:00 2001 From: Michael West Date: Thu, 19 Mar 2020 12:29:29 -0700 Subject: TwinRX: Remove decimation from frontend The decimation in the rx_frontend_gen3 was added to reduce the bandwidth between the Radio and the DDC due to the limitation in bandwidth over the crossbar for dynamically connected blocks. The default FPGA image for the X300 now has a static connection between the Radio and DDC, so this is no longer necessary. This change allows the TwinRX receive channels to be time aligned with channels from other daughterboards so they can be used in the same streamer.
