SP505 Multi–Mode Serial Transceiver
Copyright 2004 Sipex Corporation
The
SP505
is a monolithic device that supports eight (8) popular serial interface standards for DTE to
DCE connectivity. The
SP505
is fabricated using a low power BiCMOS process technology, and
incorporates a Sipex patented (5,306,954) charge pump allowing +5V only operation. Seven (7) drivers
and seven (7) receivers can be configured via software for any of the above interface modes at any time.
The
SP505
requires no additional external components for compliant operation for all of the eight (8)
modes of operation. All necessary termination is integrated within the
SP505
and is switchable when
V.35 drivers, V.35 receivers, and V.11 receivers are used. The
SP505
can operate as either a DTE or DCE.
Additional features with the
SP505
include internal loopback that can be initiated in either single-ended
or differential modes. While in loopback mode, driver outputs are internally connected to receiver inputs
creating an internal signal path convenient for diagnostic testing. This eliminates the need for an external
loopback plug. The
SP505
also includes a latch enable pin with the driver and receiver address decoder.
Tri-state ability for the driver and receiver outputs is controlled by supplying a 4-bit word into the address
decoder. Seven (7) drivers and one (1) receiver in the
SP505
include separate enable pins for added
convenience. The
SP505
is ideal for WAN serial ports in networking equipment such as routers,
switches, DSU/CSU's, and other access devices.
