KE5BCCA1M

www.DataSheet4U.com KE5BCCA1M Kawasaki LSI’s Classification CAM has a capacity of 1Mbit (Ternary) and 2 Mbit (Binary), and can be configured by bank in a mixture of binary and ternary modes. Its primary application is in search and filtering. Its flexibility, high speed, and high capacity make it appropriate for all Layer 2/3/4 and above applications such as switches and routers in 10/100/1000 Ethernet, Terabit Ethernet ,OC-3/12/48/192, T1/T3, frame relay, ATM, xDSL and DWDM. This Classification CAM is also suitable for QoS applications with its unique and patent-pending “Auto Shift” commands. The search time is 15ns and the KE5BCCA1M is available in a 324-pin BGA. FEATURES: High density: 2Mbits Binary, 1Mbit for Ternary Organization: Configurable table width; binary/ternary selected by bank Binary case: 68-bit x 32k, 136-bit x 16k, 272-bit x 8k Ternary case: 68-bit x 16k, 136-bit x 8k, 272-bit x 4k High Speed Search :15n sec (1 phase clock) Latency: 30n sec (2 clock cycles) Dual-Port Architecture: 68-bit I/O port with 1. 64-bit data bus (optional 32-bit configuration) 2. Optional 4 extra bits on the data bus 3. 32-bit output port Cascadable up to 32 pieces OEDATN DAT<63:0> EDAT<3:0> DATWDT EXTONN Mask Registers CLK PHASE RSTN Decoder Pipeline Execution Control Empty Bit CSTN CEN RWN CNTL<18:0> SAD EAD 136 bits x 8192 CAM 136 bits x 8192 Local Mask Search Logic Control Logic I/O Port Control Classification CAM Support for automatic data...
