Conflicts:
	firmware/common/si5351c.c

Preferred Si5351C configuration that drives 40MHz into the LPC43xx GP_CLKIN.
Added HACKRF_ONE qualifier for CPLD TMS/TDI swap.

7f35ceaff2 Set Si5351C CLK7 output to drive LPC GP_CLKIN at 40MHz, so that activity (e.g. audio) on the LPC can be synchronized with the baseband sample rate. 2013-12-31 20:09:44 -08:00

06da7fd83a Reduce drive strength from clock generator (Si5351C) to first mixer (RFFC5072). This reduces every-50MHz spurs in RX by 10 to 15dB. 2013-09-22 11:54:37 -07:00

cbd2d98c7d fixed bad output spectrum. problem was P3 = 0 in si5351c pll, similar to commit b595de647077f208c534e4efc0bce92f25378fb8 2012-08-22 10:41:53 -06:00

9a53fd3a07 New CPLD .svf.
Change Si5351C CLK2 to 10MHz.
Keep CLK3 at 20MHz, but not inverted.
Source SGPIO8 from P1_12 instead of P9_6. (See "SGPIO Clock Routing") modification at https://github.com/mossmann/hackrf/wiki/Future-Hardware-Modifications ).

02f61f4d64 Added r_div argument to si5351c_configure_multisynth(). Modified Jellybean clock setup to provide 10MHz clock to MAX5864 and 20MHz to CPLD (both inverted and non-inverted). 2012-06-13 17:53:10 -07:00
