Hardware FAQ: (Updated 04/17/09)
These are a compilation of questions our customers have asked over time, and as more questions are asked they will be added to this page.
1) What is the maximum rate for an E2D ?
2) How many I/O modules can be installed on a PIC4T, PIC4X, PIC5XL, or PIC6?
4) Which I/O modules are available for the ICE-PIC5XL or PIC6?
5) What do the dip switches/Jumpers on the side of the card do ?
6) What is the recommended clock level for an A2D-r7 ?
7) What are the connections on the A2D-r7 ?
8) What are the technical specifications on the programmable clock on the ICE-PIC4T ?
9) What are the clocking options on the SlimPIC-a ?
10) What is the pinout for the I/O module ribbon Cable ?
1) What is the maximum rate for an E2D ?
100mhz
2) How many I/O modules can be installed on a PIC4T, PIC4X, or PIC5XL ?
Each card can be populated with up to two I/O modules. In addition to the I/O modules the PIC4X can be populated with up to one processor module, and the PIC5XL can be populated with up to two processor modules.
If your card won't reset there is a chance you have a card that has not been upgraded with a particular diode. Please click the following link for more information.
4) Which I/O modules are available for the ICE-PIC5XL or PIC6?
As of 04/17/09 the following modules are in production and available for the PIC5XL or PIC6:
ICE-A2D-r8, ICE-A2D-r13, ICE-D2A-r9, ICE-Sonet-r4, ICE-Sonet-r5, ICE-E2D-r5, ICE-D2E-r5, ICE-UDP-r5-CPR and FBR
ICW-DR2D, ICE-A2D-r10, ICE-A2D-r11, ICE-LV2D, ICE-D2LV
5) What do the dip switches/Jumpers on the side of the card do ?
The edge connector has 1 SMB connector to provide an external clock for output modules or a signal for synchronizing multiple cards. There are 3 dip switches for configuring the external clock/sync connector:
J1 - close for on board 50 ohm termination, open for high impedance
J2 - close for multi-board signaling (external sync), open for clock
J3 - close for DC coupled TTL clock, open for AC coupled 1Vpp sinusoid clock
The standard configuration when the cards are shipped from ICE is J1 closed with J2 and J3 open.
PIC4T, PIC4X, and PIC5XL
PIC6 **Please note even though there are four dip switches on the PIC6, only the first three are connected.**
Note: on some early (PIC3 or earlier) models the dip switches are just jumpers. To synchronize acquisition/playback between multiple cards, J2 must be in place (closed) for both the master and slaves. The Master asserts the XSOE flags to drive the line. The J1 terminators should be open. Add J3 for 2.5V 10kohm pull-up/dn and diode protection on the input/output. One on-board crystal X2 is socketed for an optional user supplied reference clock. This clock can be used for driving A2D or D2E modules at fixed rates or for special IOC code rates. By default, X2 is a 100MHz clock for maximum bandwidth A2DR7 clocking.
6) What is the recommended clock level for an A2D-r7 ?
1Vp-p, 3 dBm
7) What are the connections on the A2D-r7 ?
(Two A2D-r7s on a PIC Card)
8) What are the technical specifications on the programmable clock on the ICE-PIC4T ?
The programmable clock on the ICE-PIC4T can be used from 100KHz -105MHz. It will settle to within 1000ppm of the desired rate.
9) What are the clocking options on the SlimPIC-a ?
C-clock = 64MHz, I-Clock = 40MHz, and an external clock. (Both C and I are accurate within 100 ppm) If you use an external clock please keep in mind it must be a square wave between 0 - 3.3v. **Anything over 3.3v could ruin the front end of the card since there is no comparator on board.** The input impedance is 50 ohm.
