DESCRIPTION
The SP3508 is a monolithic device that supports eight (8) popular serial interface standards
for Wide Area Network (WAN) connectivity. The SP3508 is fabricated using a low power
BiCMOS process technology, and incorporates a Sipex regulated charge pump allowing
+3.3V only operation. Sipex's patented charge pump provides a regulated output of +5.5V,
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 SP3508 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 SP3508 and is switchable when V.35
drivers and V.35 receivers, or when V.11 receivers are used. The SP3508 provides the
controls and transceiver availability for operating as either a DTE or DCE.
Additional features with the SP3508 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 SP3508 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 SP3508 include separate enable pins for added convenience. The SP3508 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.

These are stress ratings only and functional operation of the
device at these ratings or any other above those indicated in the
operation sections of the specifications below is not implied.
Exposure to absolute maximum rating conditions for extended
periods of time may affect reliability.
STORAGE CONSIDERATIONS
Due to the relatively large package size of the 100-pin quad flat-
pack, storage in a low humidity environment is preferred. Large
high density plastic packages are moisture sensitive and should
be stored in Dry Vapor Barrier Bags. Prior to usage, the parts
should remain bagged and stored below 40°C and 60%RH. If
the parts are removed from the bag, they should be used within
48 hours or stored in an environment at or below 20%RH. If the
above conditions cannot be followed, the parts should be
baked for four hours at 125°C in order to remove moisture prior
to soldering. Sipex ships the 100-pin LQFP in Dry Vapor
Barrier Bags with a humidity indicator card and desiccant pack.
The humidity indicator should be below 30%RH.
