1 ps8365e 08/24/99 product description pericom?s pi5x series of high density logic circuits are pr oduced using the company?s advanced submicron cmos technology to achieve industry leading performance. the PI5X1018 is an 18-bit, 10-port crossbar switch designed with a low on resistance allowing inputs to be connected directly to outputs. the crossbar creates a low propagation delay and adds low additional ground bounce noise. switches are turned on in groups of 18 allowing any combination of connected ports. an additional bias voltage pin, vbias, permits control of internal pull-up resistors that can be used for pin termination. several of these devices can be grouped together for wider data and control paths. product features ? full 10-way crossbar ? independent controls for all ports ? multiple parts can be used for wider data paths ? near-zero propagation delay ? 25 w switches connect input to outputs ? direct bus connection when switches are on ? ultra low quiescent power (1ma typical) ? packages available: - 256-pin bga (na256) applications ? digital network switching: - hubs & routers - atm switch systems - backbone access routing - add drop multiplexing ? multiprocessor systems switching ? large memory bus switching ? video signal routing & image processing ? telecommunications switching ? raid systems bus switching logic block diagram truth table * specify low numbered port first n o i t c n u fn i pe t a t s * d e t c e n n o c m t r o p - n t r o ps m - n w o l * d e t c e n n o c s i d m t r o p - n t r o ps m - n h g i h 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 2123456789012 1 2345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012 12345678901 2 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 2123456789012 PI5X1018 18-bit, 10-port crossbar switch
