KAWASAKI MICROELECTRONICS
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.
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
· Support for automatic data shifting
· Continuous search during data shifting.
· Multi-hit support (highest hit address output)
· 18 Global MASK Registers (68-bit width) for data search/writing operation.
· Automatic learning
