SP508
Rugged 40Mbps, 8 Channel Multiprotocol Transceiver
with Programmable DCE/DTE and Termination Resistors
DESCRIPTION
The
SP508
is a monolithic device that supports eight (8) popular serial interface standards for
Wide Area Network (WAN) connectivity. The
SP508
is fabricated using a low power BiCMOS
process technology, and incorporates a Sipex regulated charge pump allowing +5V only
operation. Sipex's patented charge pump provides a regulated output of +5.8V, which will provide
enough voltage for compliant operation in all modes. Eight (8) drivers and eight (8) receivers can
be configured via software for any of the above interface modes at any time. The
SP508
requires
no additional external components for compliant operation for all of the eight (8) modes of
operation other than four capacitors used for the internal charge pump. All necessary termination
is integrated within the
SP508
and is switchable when V.35 drivers and V.35 receivers, or when
V.11 receivers are used. The
SP508
provides the controls and transceiver availability for
operating as either a DTE or DCE.
Additional features with the
SP508
include internal loopback that can be initiated in any of the
operating modes by use of the LOOPBACK pin. While in loopback mode, receiver outputs are
internally connected to driver inputs creating an internal signal path bypassing the serial
communications controller for diagnostic testing. The
SP508
also includes a latch enable pin with
the driver and receiver address decoder. The internal V.11 or V.35 termination can be switched
off using a control pin (TERM_OFF) for monitoring applications. All eight (8) drivers and receivers
in the
SP508
include separate enable pins for added convenience. The
SP508
is ideal for WAN
serial ports in networking equipment such as routers, access concentrators, network muxes,
DSU/CSU's, networking test equipment, and other access devices.
