| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Looks like product datasheets for tuners containing STB0899 are suggesting specification for min. symbol rate of 2MS/s. Some specs found here, all suggesting 2MS/s for min. symbol rate: Comtech DVBS2-6899 http://comtech.sg1002.myweb.hinet.net/pdf/dvbs2-6899.pdf TechniSat SkyStar HD2 http://www.scaistar.com/skystar2/skystarhd2.htm Azurewave AD-SP400 http://www.pulsat.com/products/AzureWave-AD%252dSP400-High-Definition-PC-Card.html New patch: This makes minimum symbol rate driver capabilities on par with some accessible datasheet specifications*, and allows tuning on linux to transponders that have symbol rate between 2000000-5000000, too. Patch was tested successfully on Eutelsat 16A transponders that became reachable with it (2000000 < symbol rate < 5000000): * DVB/S 12507050 V 2532000 3/4 * DVB/S2 12574000 V 4355000 3/4 8PSK * DVB/S 12593000 V 2500000 2/3 * DVB/S 12596940 V 2848000 2/3 * DVB/S 12600750 V 2500000 1/2 * DVB/S 12675590 H 4248000 3/4 (*) Datasheet: http://comtech.sg1002.myweb.hinet.net/pdf/dvbs2-6899.pdf Maximum Symbol Rate QPSK/LDPC/PCH: 20-30Mbps 8PSK/LDPC/BCH: 10-30Mbps DVB: 2-45Mbps ^--------- min. symbol rate Signed-off-by: Zoran Turalija <zoran.turalija@gmail.com> Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] stb0899: fix inversion enum values to match usage with CFRReinhard Nißl2013-06-082-4/+4
| | | | | | | | | | | | | | | | | | | Throughout the zig-zag-implementations, inversion is taken into account when reading and writing the CFR register, which contains the derotator frequency. As swapping IQ signals changes the sign of that register for example, the idea is to compensate that sign change by multiplying the register value with the inversion enum value. The current enum values 0 and 1 for IQ_SWAP_OFF and IQ_SWAP_ON don't work in the case IQ_SWAP_OFF, due to the multiplication by zero (I've only found a single device which actually uses IQ_SWAP_OFF in it's config). I've changed the enum values to +1 and -1 to accommodate to the intended usage.
