V1.1
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
64-bit data bus (optional 32-bit configuration)
Optional 4 extra bits on the data bus
32-bit output port
Cascadable up to 32 pieces
