5 - Jumpers to gnd for TXBLANK.
6 - Unpopulated resistors for redoing SPI, shared with io_tx_a/b[15]
8 2004-11-03 Matt Ettus <matt@ettus.com>
10 * fpga.sch : Removed J900 and J902 which were to test the FX2 bus.
11 The lines were just too long.
13 2004-10-27 Matt Ettus <matt@ettus.com>
15 * power.sch : Removed text note
17 * dboard.sch : Swapped RS-232 so that each board gets a pair, shared between RX and TX
20 - Removed U410 (MAX232) and associated caps
21 - Rerouted RS232 signals so they go out as CMOS levels
22 - Removed J645 which was PE[2:0]
25 - Redid FX2 bus interface probe pins on J900
26 - Added J902 with FX2 data bus
28 2004-10-23 Matt Ettus <matt@ettus.com>
31 - Added command script for generating a netlist
33 - Added J1001 for ground testpoints
34 - Added C0603 footprint to a bunch of caps.
36 2004-10-10 Matt Ettus <matt@ettus.com>
39 - Remove io_tx_b_15 from VCXO tuning, remove R800,R803,R876,C800,C804
40 - Connect X2.1 to DVDD
41 - Removed nets CLKOUT1_x and CLKOUT2_x
42 - Removed R801, R802, R857 -- CLK120 now goes straight to FPGA
44 - Split CLK120 into CLK_FPGA, CLK_CODEC_A, and CLK_CODEC_B, each with proper source and sink terminations. Use 50 ohm lines.
45 - Added R1011-R1016 and C1014-C1016 for terminations
46 - Added MYSTERY_SIGNAL to replace one RX_SYNC
47 - Moved SDO to where TX_BLANK was
48 - Moved SDI to one RX_SYNC
49 - Moved SEN_FPGA to where RESET was
52 - Removed CLKOUT1_x and CLKOUT2_x
53 - Removed io_[tx,rx]_x_16 which never did anything
56 - Added MYSTERY_SIGNAL input to INT4
60 - Added C1020 for more decoupling of 5V
61 - Increased value of C502 to 100 uF
63 2004-10-08 Matt Ettus <matt@ettus.com>
66 - Reset on PC0 is now RESET_CODEC
67 - Tool changed format of Text items
68 - NB - Need to find pin for RESET_FPGA. Maybe PE0,1,2 or FX2_1. Send rest to dboard?
71 - R701, R702 changed from 2K to 4K, to fit what the datasheet tells us.
72 - R1001,R1002,R1003,R1004,C1001,C1002,C1003,C1004 added to do sigma delta filtering on the motherboard
73 - Net SIGDEL_x no longer goes to dboard. It gets filtered, and AUX_DAC_D_x is sent
74 - RESET on CODECs and Dboards is now RESET_CODEC
75 - Tool changed format of Text items
76 - NB - Should we avoid sending REFIO_x to the dboards for sig integrity?
77 - NB - Get rid of io_tx/rx_x_16
78 - NB - Find a bit 15 for io buses
