ICE-A2D-M14
The ICE A2D-M14 is a 14-bit A/D module for use with the ICE-PIC5, ICE-PIC6, ICE-PIC7, and ICE-PIC8 series of high-speed interface cards. (The latter is recommended.)
Software selection allows for the use of an onboard clock synthesizer or direct clock input at a user desired sample rate. The onboard clock synthesizer uses a 10MHz reference from either an external source (J2) or via an onboard oscillator (TCXO).
The A2D-M14 module incorporates a variable gain input stage, which 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:
- Operation using external reference of 10MHz replaces the external clock input. Sample clock is then generated from the 10MHz reference.
- Sample rates below 40 MSPS require decimation flag in module configuration.
