2008-01-18Bug: Bandwidth calculationManu Abraham
Bug #1: The 5 tap equaliser is set to correct simple perturbations like reflections on the IF cable for DVB-S. In the case of DVB-S2 a more powerful equalizer is used to correct the filter group delay allowing the bandwidth to be reduced by a factor of 1/3 Bug #2: The ZIF tuner takes badwidth to be set in Hz From: Manu Abraham <abraham.manu@gmail.com> Signed-off-by: Manu Abraham <manu@linuxtv.org>
2007-11-19Revert back previous change to 90MHzManu Abraham
Note: * At High Symbol Rates we do not have enouph machine cycles to handle the incoming symbols and hence might run into problems at the very end of the specified definition * Most of the equations have been calculated for a master clock of 99 MHz, running at 90MHz, raises lot of issues such as the need to recalculate all of them , which is eventually very painful.

2007-11-10Bug! SFRL nibble got swappedManu Abraham
The Bug was found by Arvo Jarve <arvo@softshark.ee> It was a wonder how it worked in the case with this bug, STM verified this that this nibble was in fact insignificant and can be ignored. But still we need to fix all inconsistencies. From: Manu Abraham <abraham.manu@gmail.com> Signed-off-by: Manu Abraham <manu@linuxtv.org>

2007-10-30Limit bandwidth with a 3dB response fallManu Abraham
In this case, we will be sure that there exists a carrier and the center frequency would be simply f1 - f2. In such a circumstance, the TR loop is simplified to doing a simple check for timing, rather than searching for the same.

2007-10-30BUG! Setting CRL parameter overwrote the CR Algorithm type,Manu Abraham
eventually leading to wrong search algorithm to be employed in the DVB-S carrier loop optimization. Symptom: Once the CR optimization stage is passed either way, in a successful or failed manner, the very next carrier search will fail, due to no Carrier Search Algorithm specified.

2007-10-15Though insignificant, removes an unnecessary read of the LOCK_LOSS register,Manu Abraham
which should have happenend in the DVB-S2 mode only, but reading it as it is for the other delivery systems causes nothing to say but LOCK_LOST, which just causes confusion amongst users. From: Manu Abraham <abraham.manu@gmail.com> Signed-off-by: Manu Abraham <manu@linuxtv.org>
