2004-11-22 Matt Ettus * fpga.sch : - Added R2001-R2005. - Jumpers to gnd for TXBLANK. - Unpopulated resistors for redoing SPI, shared with io_tx_a/b[15] 2004-11-03 Matt Ettus * fpga.sch : Removed J900 and J902 which were to test the FX2 bus. The lines were just too long. 2004-10-27 Matt Ettus * power.sch : Removed text note * dboard.sch : Swapped RS-232 so that each board gets a pair, shared between RX and TX * interface.sch : - Removed U410 (MAX232) and associated caps - Rerouted RS232 signals so they go out as CMOS levels - Removed J645 which was PE[2:0] * fpga.sch : - Redid FX2 bus interface probe pins on J900 - Added J902 with FX2 data bus 2004-10-23 Matt Ettus * netlist_cmd : - Added command script for generating a netlist * power.sch : - Added J1001 for ground testpoints - Added C0603 footprint to a bunch of caps. 2004-10-10 Matt Ettus * fpga.sch : - Remove io_tx_b_15 from VCXO tuning, remove R800,R803,R876,C800,C804 - Connect X2.1 to DVDD - Removed nets CLKOUT1_x and CLKOUT2_x - Removed R801, R802, R857 -- CLK120 now goes straight to FPGA - Removed J901 - Split CLK120 into CLK_FPGA, CLK_CODEC_A, and CLK_CODEC_B, each with proper source and sink terminations. Use 50 ohm lines. - Added R1011-R1016 and C1014-C1016 for terminations - Added MYSTERY_SIGNAL to replace one RX_SYNC - Moved SDO to where TX_BLANK was - Moved SDI to one RX_SYNC - Moved SEN_FPGA to where RESET was * dboard.sch : - Removed CLKOUT1_x and CLKOUT2_x - Removed io_[tx,rx]_x_16 which never did anything * interface.sch : - Added MYSTERY_SIGNAL input to INT4 * power.sch : - Removed D501 - Added C1020 for more decoupling of 5V - Increased value of C502 to 100 uF 2004-10-08 Matt Ettus * interface.sch : - Reset on PC0 is now RESET_CODEC - Tool changed format of Text items - NB - Need to find pin for RESET_FPGA. Maybe PE0,1,2 or FX2_1. Send rest to dboard? * dboard.sch : - R701, R702 changed from 2K to 4K, to fit what the datasheet tells us. - R1001,R1002,R1003,R1004,C1001,C1002,C1003,C1004 added to do sigma delta filtering on the motherboard - Net SIGDEL_x no longer goes to dboard. It gets filtered, and AUX_DAC_D_x is sent - RESET on CODECs and Dboards is now RESET_CODEC - Tool changed format of Text items - NB - Should we avoid sending REFIO_x to the dboards for sig integrity? - NB - Get rid of io_tx/rx_x_16 - NB - Find a bit 15 for io buses
