preliminary posic2gvc?/posic2g ? evaluation boa rd cyposic2gvc- k cypress semiconductor corporation 3901 north first street san jose , ca 95134 408-943-2600 document #: 38-02028 rev. *b revised may 9, 2003 purpose this board is intended for two purposes. the first is as a demonstration of the capabilities of the (packet-over-sonet integrated circuit) posic2gvc ? device. the second is as a development platform for the system designer who wants to evaluate the posic2gvc device, to create custom logic to interface with posic2gvc, and to implement their own functionality. features the features of this board include: cypress posic2gvc device cypress high-performance no bus latency ? (nobl ? ) ram, 12 mbytes cypress cys25g0101dx oc-48 sonet/sdh phy cypress delta39k ? cpld cy39100v388-200mgc motorola mpc860 processor, operating at 66 mhz two 300k gate fpgas, each scalable to 600k gates ocp optical modules, 1310-nm wavelength four independent clock sources on the board 16 mbytes of sdram 1 mbyte of flash memory codec and handset for communication over orderwire bytes. standard mictor connectors are used on all buses for external driving and observing signals.this permits the user to directly control all aspects of the board?s operation. the evaluation board is powered by an external 3.3v power supply. the board also has a 5v power supply connector, to supply 5v to the 266-pin mictor connector on the board. external interfaces the following signals are brought out through connectors: rs 232 debug port utopia/spi-3 level 3 signals toh serial data interface processor data, address and control signals jtag signals bdm signals posic2gvc-sonet transmit and receive parallel data bus nobl sram interface signals telephone handset 4-wire interface posic2gvc debug port interface. the evaluation board is a free-standing, 12-layer pcb with mounting holes for support. see figure 5 for an example using the mictor connectors to replace the motorola cpu with another device. cypress cpld cy39100v388- 200mgc cypress quad hotlink ii cyp15g0401dx serdes xilinx fpga 1 xilinx fpga 2 cypress posic2gvc cypress nobl ram cy7c1370b cypress cys25g0101dx oc-48 serdes ocp optical module motorola mpc860 processor 16 mbytes sdram 1 mbyte boot flash telephone handset jack oki semi codec msm7717-01 data, control, address bus mictor connector to observe and drive bus mictor mictor mictor mictor rs232 interface to cpu figure 1. posic2gvc evaluation board block diagram
