Notes on AED-200 Mounting

Revised 5/7/01

Mounting of Devices in Breadboard Areas:

1. Mounting is done as a service by Signalware to customers of the AED-200 board. Signalware mounts mixed signal device and buffer amplifiers at fixed prices quoted in the data sheet. Signalware does NOT supply the parts for mounting.
2. Mixed signal devices are mounted in the 42 position mounting area closest to the FPGA (called mixed signal mounting area). Mixed signal devices may include A/D and D/A converters, comparitors, and a variety of buffer devices that have TTL compatible digital connections on one side and other types of signal connections on the other. RS422 transmitters and receivers are an example of such a device.
3. Any brand of device can be mounted. Only TI parts are listed in the tables; however, on request Signalware will provide the number of positions required for any other applicable brand of device.
4. The devices that can be mounted must have SOIC and wide SOIC surface mount packages. These packages have 50 mil pin spacing and are between 300 mil and 600 mil wide (outside pin dimension). In TI devices, the appropriate package codes are D and DW.
5. Charges for mounting are based on the number of positions that the A/D, D/A or buffer device occupies in the mixed signal breadboard area as shown in the data sheet parts or as quoted by Signalware. Mounting fees apply to each device mounted. Quantity pricing does apply. Generally up to 42 positions total of all mixed signal devices can be accommodated. In some special cases, more than 42 can be accommodated. Signalware will quote particular combinations to meet customers needs.
6. It is the customers responsibility to deliver the devices for mounting to Signalware. At least one extra device of each type should be provided in case of a problem during mounting or testing. Signalware is not responsible for damage to devices or loss of devices during mounting. Extra samples are returned to the customer with the product. The devices must be delivered to the following address within 3 working days of the start of the order:

   3895 N. Cascade Avenue, Suite 201
   Colorado Springs, CO 80907
   719-593-0509

7. Signalware can not order samples from a vendor and mount them. Samples are restricted to use by the ordering company and can not be sold.
8. For small quantities, it would be generally appropriate for the customer to obtain samples of the devices for mounting from the appropriate vendor. TI device samples can be ordered on the TI web site and drop shipped directly to Signalware for mounting at the address above.
9. Signalware positions the devices for mounting in the mixed signal area to get the maximum separation between D/A and A/D devices. All connections to the device are made with surface mount components if possible. Some connections for some devices are made with a #28 or #30 wire wrap wire when necessary. Pins are generally connected in the following way depending on the type of pin:

   PIN TYPE DESTINATION INTERMEDIATE COMPONENTS

   • Digital Ground Digital Ground Plane None (except jumpers, generally 2)
   • Digital 3.3 V Digital 3.3 V supply Series ferrite bead and bypass capacitor
   • Digital 5.0 V Digital 5.0 V supply Series ferrite bead and bypass capacitor
   • Digital Clock FPGA Terminating resistor to ground
   • Digital Signal FPGA None (except jumpers, generally 2)
   • Analog Ground Analog Ground Plane None (except jumpers, generally 2)
   • Analog 5.0 V Analog 5.0 V supply Series ferrite bead and bypass capacitor
   • Other Analog V 5 or 12 V supply Series regulator and bypass capacitor
   • Analog Reference 1.024, 2.048, 4.096 V Series ferrite bead and bypass capacitor
   • Analog Signal In 50 pin analog connector Load resistor, series 1 pole filter
   • Analog Signal Out 50 pin analog connector None (except jumpers)
10. Buffer amplifiers are mounted in the general breadboard area connected between the 50 analog connector and the mixed signal area. These devices must have SOIC or wide SOIC surface mount packages or .3? or .6? through-hole DIP packages. Customer may supply any amplifier for mounting that meets these requirements. Several D/A devices on the market are current mode devices that require an amplifiers to produce an output voltage. Signalware will generally quote amplifiers for these devices, unless requested to do otherwise, if we are aware that the amplifier is needed. This does not relieve the customer of the responsibility for ordering amplifiers as needed for the particular application.
11. For devices operating above 5 MHz analog signals, the lead lengths inherent in the mixed signal and general breadboard area may adversely affect performance of the device. Signalware wires the mounted devices in a standard way to test that the devices are operational. Signalware does not test the performance of the devices. For higher speed devices, it may be necessary for the customer to disconnect the analog wiring and add circuitry in the breadboard to provide appropriate signal conditioning.
12. Digital wiring is usually adequate for 50 MHz digital signals in the mixed breadboard area. FPGA Configuration charges:

    a. The FPGA configurations provided with the boards that have devices mounted on them are for testing the operation of these devices. These configurations are NOT custom programs for the customers applications. They are provided to the customer in order to allow the customer to recheck the operation of the board upon receipt. Signalware provides the source for the configurations to the customer, and the customer may find the configuration is a useful example to begin designing custom applications.

    Signalware encourages the customer to review the test configurations and use them to best advantage. Ownership of the configuration remains with Signalware, and the customer may not resell the configuration without express permission of Signalware. Signalware will quote custom FPGA configurations if requested.

    b. The charges for configuration are mandatory if Signalware mounts devices for the customer. The fees are one time per device type per customer. Quantity pricing does not apply. If the customer subsequently orders additional board(s) with the same device type mounted, the FPGA configuration charge from the initial order applies to the subsequent order.

    c. Signalware reserves the right to elect subsequently to advertise and/or sell a particular configuration supplied to a customer as a standard configuration. In accepting this quotation, the customer waives the right to any royalties or other benefits from Signalware's use of the configuration. The price may be less than that charged to the initial customer(s). If so, the customer(s) is (are) not entitled to a rebate, however, the customer(s) may take advantage of the lower standard item pricing for subsequent orders.
