7 S2090 68 x 69 3.2 gbps differential crosspoint switch may 31, 2001 / revision nc parallel read function the parallel read function allows the user to access stored data, either in the configuration register file or in the active configuration latch. this feature guarantees, prior to asserting confign low (configuration register moved to active matrix), that the S2090 is configured to the user's satisfaction. the read function also serves as a checker to see if both the configuration register file and the active configuration latch are being programmed correctly by the software. the read function includes two pins, rdcfgn and rdactn. rdcfgn selects the configuration register, while the rdactn pin se- lects the active configuration latch. also included is an eight-bit parallel bus, rdata[7:0]. the data stored in either the configuration register file or the active con- figuration latch (determined by rdcfgn or rdactn) will be read out on this bus. rdata[7] is the power enable bit and rdata[6:0] is the input address. as the rdcfgn or rdactn is held low (only one can be set low at a time), an oaddr[6:0] must be applied to the device to read out the data that is being requested. when rdcfgn or rdactn is low, the iaddrs and oe are ignored, therefore no changes in the iaddrs or oe can occur in the latches. the S2090 can be read or written to, but read and writes can not occur at the same time. simultaneous reads and writes are not allowed, so confign and loadn must remain high while rdcfgn or rdactn is low. see figure 9 for write-to- read and read-to-write waveforms. the parallel read data waveforms are shown in figures 6 and 7. figure 8 shows how to check multiple registers by switching oaddrs one after another and asserting rdcfgn or rdactn low during the cycling time. user note (parallel read back) this section of text can be ignored if not using the parallel read back feature. when operating the S2090 with a 2.5 v power supply, the drive capability of the rdata[7:0] bits is not optimal. the parallel read back bits (rdata[7:0]) have to be buffered to meet the vih minimum limit of typical lvttl or lvcmos circuits. the voh minimum presented on the rdata[7:0] out- puts is 1.8 v under worst-case conditions. a small 8-bit buffer can be used to resolve this issue. texas instru- ments has a small packaged buffer that will accept the reduced voh limit from the rdata[7:0] bits and in- crease the signal amplitude to provide the correct lvttl or lvcmos input limits, part number sn74lvc541a. there are an abundance of these types of buffers available from multiple vendors. activate csn configure oaddr[6:0] to desired output. see table 1. configure iaddr[6:0] to desired input. see table 1. strobe loadn to store the input address (iaddr[6:0]) in the section of the configuration register file pointed to by the output register (oaddr[6:0]) configure another output? strobe confign to store all connections to the active configuration latch yes no figure 5. S2090 configuration flow chart reset behavior during a resetn assertion, all the output drivers are powered down. the p and n side of the differential output signals will be pulled up to v cc . the ic will not pass data through the matrix until the inputs and outputs are explicitly reconfigured to be enabled and powered up using the oe signal. power up upon power up, the crosspoint will default to full broad- cast mode (dinxx to all the outputs, dout0 through dout68). dinxx is determined by the state of the bits on iaddr[6:0] at the moment the device is powered up. the oaddr[6:0] and oe bits will not have any affect on the configuration of the switch at power up. the ic will remain in full broadcast mode until the inputs and outputs are explicitly reconfigured to be enabled.
