Dual 1.6 GSPS Analog to Digital Input Module
Notice: End-of-Life has been announced for this product. It has been superseded by the ICE-A2D-M20. Please see End-of-Life for details.

The ICE-A2D-M18 is a dual-channel 12-bit analog-to-digital converter module for use with the ICE-PIC and ICEPOD series of high-speed interfaces.

The module is equipped with an onboard sample clock synthesizer, which can be configured to 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-M18 module incorporates a variable gain input stage. The variable gain stage allows independent channel gain settings from -40dB to +20dB in 1dB steps and is user software controlled. Additionally, the variable gain stage can be used to mute or completely disable 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.

  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 150 MSPS require decimation flag in module configuration.

Absolute Maximum Ratings

Parameter Value
5.0 VDC
DVcc 3.3 VDC
PPS Input 0 to 6 Vpeak into 50 Ohm
External Clock Input 0 to 6 Vpeak into 50 Ohm
Analog Input Power 0 dBm (50 Ohm ref)
Operating Temperature -10 to +65 °C
Storage Temperature -40 to +85 °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.
