Product Information
The Technobox, Inc. P/N 9413 High-Drive/Voltage is a VITA 20 conduction-cooled PMC offering 64-bits of digital I/O available at the PN4 connector. A PLX/Broadcom 9056 bridge chip provides a 32-bit, 33- or 66- MHZ PCI interface to a local bus, which is connected to an Altera 5CGXFC4C6F27I7N FPGA.
The I/O side of the FPGA is handled with 5V-powered 74ABT126 drivers and 5V-powered 74LVC8T245 receivers, which also translate the signals to 3.3V levels for use by the FPGA. The drivers are capable of -32ma IOH and 64ma IOL, making it suitable for VME-level signaling and other older 5V technologies.
The 9413 can also be populated with other 74xxx126 drivers, including those for 3.3V powered devices. If there is a unique requirement, Technobox, Inc. will assign a separate, orderable part number.
Each of the 64 DIO channels has a resistor population option to disconnect the I/O and tie it to ground, or series terminate with a specified resistor. The default deliverable (ie, P/N 9413) has all channels connected to the I/O pin through a zero-ohm resistor.
The FPGA and the associated 128Mb (16MB) FLASH memory that downloads FPGA code during power up can be programmed by a JTAG header located on the 9413 board, using a customer supplied USB Blaster or equivalent. Alternatively, the FLASH memory can be programmed over the PCI bus if the IP exists in the initialized FPGA to support this mode.
The design also features a temperature sensor and EEPROM for customer parameters, if needed, connected to the FPGA. 9413 uses all Industrial Temperature Range (I-temp -40 to +85 Deg C) parts and is built with RoHS solder and components.
