SP504CF中文资料西伯斯数据手册PDF规格书

The introduction of our SP502 transceiver paved the way for a new generation of multi-mode transceivers that are being designed into next generation networking products. The SP504 multi-mode transceiver is the latest member of the family and offers: reduced external V.35 termination; V.36 & EIA-530A modes; and receiver tri-state and fail-safe ability.

As with the SP502 and SP503, the SP504 can be programmed via software to the different available physical protocols and is also drop-in compatible with its predecessors.

The versatility of the SP504 is ideal for multiprotocol applications such as Frame Relay systems, X.25 routers/switches and multi-protocol routers. These multi-protocol systems will usually contain multiple ports to accommodate the different interfaces. The SP504 can support all the ports through software and provide convenient DTE or DCE functionality to the port. DTE and DCE configuration is provided on the next page and also in the SP504 data sheet.
