GENERAL DESCRIPTION
The SP510 is a highly integrated physical layer
solution that is configurable to support multiple serial
standards. It incorporates eight (8) drivers and eight
(8) receivers, configurable for either differential (V.11
or V.35) or single ended (V.28 and V.10) signaling.
The device architecture is designed to support the
data and clock signals used in HDLC or SDLC serial
ports as either a DTE or DCE. SP510 enables a
Serial Communications Controller (SCC) to
implement a variety of serial port types including
V.24, V.25, V.36, EIA-530, EIA-530-A, X.21, RS-232.
Operating configuration is in-system programmable
using the mode-select pins. The V.11 and V.35 modes
contain built in bus termination that may be switched
in or out using the TERM_OFF pin.
SP510 is ideal for space constrained applications. It
requires only a single 5V supply for full operation.
The VL pin determines the receiver output voltage
(VOH). For single supply operation at 5V the VL pin
may be connected to VCC. Fully compliant V.28 and
V.10 driver output voltages are generated using
onboard charge pumps. Special power sequencing is
not required during system startup. Charge pump
outputs are internally regulated to minimize power
consumption. The SP510 requires only four 1µF
capacitors for complete functionality. The device may
be put into a 1µA low power shutdown mode when
not in active use.
All receivers have fail-safe protection to put outputs
into a known state when inputs are open, terminated
but open or shorted.
