SP510 Datasheet | Exar

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 munications 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 pliant 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 plete functionality. The device may be put into a 200μA 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.
