The ICE A2D-m14 is a 14-bit A/D module for use with the ICE-PIC5 or ICE-PIC6 series of high-speed interface cards (the latter is recommended).

Software selection allows for the use of an on-board clock synthesizer or direct clock input at a user desired sample rate. The on-board clock synthesizer uses a 10MHz reference from either an external source (J2) or via an on-board oscillator (TCXO).

The A2D-m14 module incorporates a variable gain input stage. The variable gain stage allows for real-time gain settings of -11dB to +20dB in 1dB steps and is user-software-controlled. Additionally, the variable gain stage can be used to mute or to disable completely analog input to the A/D.

The use of external 10 MHz and 1 PPS reference signals allows for precision time stamping of digitized data with better than 2.5 nanosecond accuracy, independent of sample rate.

Notes:

  1. Operation using external reference of 10MHz replaces the external clock input. Sample clock is then generated from the 10MHz reference.
  2. Sample rates below 40 MSPS require decimation flag in module configuration
