SP526
WAN Multi-Mode Serial Transceiver
DESCRIPTION
The SP526 is a monolithic device that sup-
ports three (3) physical layer serial interface
standards. The SP526 is fabricated using a
low power BiCMOS process technology, and
incorporates four (4) drivers and four (4)
receivers can be configured via software for
the selected interface modes at any time.
The SP526 includes tri-state ability for the
driver and receiver outputs through separate
enable lines. A shutdown mode is also
included through the mode select pins for
power savings. When mated with the SP322
V.11/V.35 Programmable Transceiver, the
SP526
provides the four (4) channels needed
for handshaking/control lines such as CTS,
RTS, etc. The two transceiver ICs are an
ideal solution for WAN serial ports in
networking equipment such as routers,
DSU/CSU's, and other access devices.
