Sealevel releases PCI Express synchronous serial interface with configurable ports

LIBERTY, S.C., 8 Feb. 2013. Sealevel is introducing 5402e, a PCI Express synchronous serial interface with four ports individually configurable for RS-232, RS-422, RS-485, RS-530, RS-530A, or V.35.

Sealevel’s new synchronous serial adapter is well suited to satellite, radar, military, and other applications that require robust synchronous communications.

It is designed with a 4-port PCIe sync board that supports the Zilog Z85230 Enhanced Serial Communication Controller (ESCC).    

In RS-232 mode, all common modem control signals are implemented for compatibility with a wide range of peripherals. For maximum compatibility with a variety of synchronous protocols, a digital phase lock loop (DPLL) is included on each port, and the board supports data rates up to 128 kilobits per second (Kbps) in burst mode. For easy implementation, a fan-out cable is included that terminates the on-board 100-pin SCSI-style connector to four DB-25M connectors. Terminal blocks, adapter cables, and other helpful accessories are available to simplify installation.

Software support, critical for successful synchronous communication development, is provided through Sealevel's SeaMAC V5 synchronous serial driver. HDLC/SDLC protocols are supported as well as certain configurations of Monosync, Bi-sync and Raw modes. All products are in-stock and pricing begins at $1,599.
