PCI (64/32 bit, 33MHz, 5V) Tuners (AD6620 x2)


				INTRODUCTION

The ICE-PIC3T is driven by an Analog Devices 21062 SHARC DSP and interfaced 
to the PCI bus by an Altera FLEX10K30 programmable logic device.  It contains 
module sites for two 16 bit digital in/outputs, a FLEX10K50 PLD for front end
bit processing, and 2 Analog Devices AD6620 Digital Tuners.

				INSTALLATION

This card fits in a standard PCI slot.  The edge connector has spacers to 
adjust to different manufacturer's chassis tolerances.  

Mounting a module requires approximately 0.6 inches of slot width.   
All external module connectors are available at the card's edge connector.

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 jumpers 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

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 65MHz clock for tuner 
upsampling or maximum bandwidth A2DR4 clocking.

NOTES: 

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

See the DRIVERS.HLP to install the software drivers.

				MAINTENANCE

Hardware checkout procedures are automated in software by running the TEST 
procedures in the PIC X-Midas macro.  Special IOC programs are loaded to
perform loopback tests for all components except the modules.
