SP510E
ULTRA HIGH SPEED MULTIPROTOCOL TRANSCEIVER
FEBRUARY 2014
REV. 1.0.1
GENERAL DESCRIPTION
The SP510E is a highly integrated physical layer
solution that is configurable to support multiple serial
standards. It incorporates eight drivers and eight
receivers (8TX/8RX), configurable for either
differential (V.11 or V.35) or single ended (V.28 and
V.10) signaling.
SP510E enables a Serial Communications Controller
to implement a variety of serial port types including
V.24, V.25, V.36, EIA-530, EIA-530-A, X.21, RS-232.
The device architecture is designed to support the
data and clock signals used in HDLC or SDLC serial
ports as either DTE or DCE.
Operating configuration is programmable in system
using the mode-select pins. The V.11 and V.35 modes
include internal bus termination that may be switched
in or out using the TERM_OFF pin.
The SP510E 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, down to 1.65V), for interfacing with
lower voltage CPUs and FPGAs. For single supply
operation at 5V the VL pin will be connected to VCC.
Fully compliant V.28 and V.10 driver output voltages
are generated using the onboard charge pump.
Special power sequencing is not required during
system startup. Charge pump outputs are internally
regulated to minimize power consumption. The
SP510E requires only four 1µF capacitors for
complete functionality. The device may be put into a
low power shutdown mode when not in active use.
All receivers have fail-safe protection to put outputs
into an output-high state when inputs are open,
shorted, or terminated but idle.
