The ICE-PIC7 is an advanced Digital Signal Processing (DSP) card for use in PCI-Express based computer platforms. Two I/O module sites and up to two processor module sites are provided. The I/O sites are capable of Direct-Digital, Analog-to-Digital, Digital-to-Analog (with IF or RF), or Bi-directional Optical module operation. One processor module (ICE-PIC7) or two processor modules (ICE-PIC7L) can be added for tune-filter-decimate applications, channelizing applications, or adding your own custom gate array code for customer specific applications. The wide range of inputs, outputs, and processing capabilities make this an excellent solution for the most demanding signal processing requirements.
The ICE-PIC7 is based on the Xilinx™ Kintex-7 FPGA, and includes a custom heat spreader. Server/Test Station installations should have sufficient internal chassis air flow across the card to maintain card status temperatures below 55 degrees C. As a reference, SAS hard disk drives in servers require temperatures less than 50 degrees C. When optimum airflow is present, typical temperatures for the PIC Card series are 40-45 degrees C.
With attached I/O Modules, the card meets PICMG requirements for single-slot occupancy. External connections to I/O modules are available at the card edge mounting plate. This mounting plate includes an SMB connector, which can be used to provide external triggering, synchronization, and DC-IRIG-B input (3.3V LVTTL level).

Input Specifications – External Reference and Triggering
|External Sine Wave Clock||50 ohm||+/- 0.5||+/- 1.0||+/- 2.0||Vp-p|
|External LVTTL Input||50 ohm||0.5||3.3||4.0||Vp-p|
Triggering Note: The trigger input is inserted on the PPS SMB connection. An LVTTL trigger is expected. An LVTTL (3.3 V) 1PPS input can be used as the trigger. Once a playback output session begins the 1st rising edge of the inbound 1PPS is read and the trigger stays high for the remainder of the playback session.
Absolute Maximum Ratings
|Storage Temperature||-40 to +85||Degrees C|
Warning: Operation of this module beyond any of these parameters may cause permanent damage. Exposure to absolute maximum ratings for extended periods may affect module reliability. Operation of the module beyond these specified parameters voids the factory warranty.
There are 4 dip switches located on the top of the card near the L-Bracket. Various configured settings are used depending on the user's application. For the switch to be ON (also designated closed) is with the switch baton toward the board. In the graphic above an arrow indicates the ON position.
- J1 – Factory Closed/On for onboard 50 ohm termination; Open/Off for high impedance
- J2 – Factory Open/Off for clock or trigger input; Closed/On for master trigger output signaling (External Trigger Source)
- J3 – Factory Closed/On for DC-coupled LVTTL clock or trigger; Open/Off for AC-coupled sinusoidal clock input
- J4 – Factory Open/Off – Switch Reserved
To synchronize acquisition/playback between multiple cards, J2 must be in place (closed) for both the master and slave cards. The master asserts the eXternal Sync Output Enable (XSOE) flags to drive the line. The J1 terminators should be open.
The PIC7's internal 8-bit test port can also be used to synchronize multiple cards. In this case, the master asserts TPOE to driver the test port and the slaves need the eXternal Trigger Go (XTGO) and eXternal Sync via Test Port (XSTP) flags.
The PIC7's onboard crystal is a fixed 100MHz clock. User crystals must be mounted on the I/O modules themselves. A programmable clock is available on the mainboard for generating digital signals.

- The headers on the board are static sensitive: Do not handle the board without taking proper static discharge precautions.
- Make sure all connectors are oriented properly.
