Specifications
Host Interface: | PCI Mezzanine Card |
Serial Interfaces: | Four UART channels each with an RS422 driver and receiver and |
| an RS423 driver. One synchronous channel with Mil. Std. 188- |
| 114A Type 1 enhanced hysteresis receivers for clock and data, a |
| 188 driver for Tx data, and an open drain PTT interface on the RTS |
| line. Another synchronous channel with RS422 driver and receiver. |
TX Data rates generated: | Up to 1.152 MHz for the UART channels. Up to 3.072 MHz for |
| the SCC in synchronous mode. Other rates are available with |
| different oscillator installations. |
Software Interface: | Control Registers, Status Ports, UART, and SCC Interface |
Initialization: | Hardware Reset forces all registers to 0, resets UART and SCC. |
Access Modes: | LW boundary Space (see memory map) |
Wait States: | 1 for all addresses except UART and SCC accesses. |
Interrupt: | Each UART channel has its own interrupt bit |
| The SCC has one interrupt bit for both channels |
| The interrupts generated by these devices depend on the setup |
| specified in the UART and SCC internal registers |
DMA: | No DMA Support implemented at this time |
Onboard Options: | All Options are Software Programmable |
Interface Options: | 68 pin twisted pair cable |
| 68 screw terminal block interface |
Dimensions: | Standard Single PMC Module. |
Construction: | FR4 |
| Components. Programmable parts are socketed. |
Temperature Coefficient: | 0.89 W/oC for uniform heat across PMC |
Power: | Max. TBD mA @ 5V |
