SP510E数据手册集成电路（IC）的驱动器接收器收发器规格书PDF

描述 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.
