ICE-A2D-r13
The ICE A2D-r13 is a 12-bit A/D module for use with the ICE-PIC5 or ICE-PIC6 (recommended) series of high-speed interface cards.
Software selection allows for 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) with sub 1 picosecond jitter performance.
The A2D-r13 module incorporates an input variable gain stage, which allows for gain settings of -4 to +20 dB in 1 dB steps and is user-software controlled.
The use of external 10 MHz and 1 PPS reference signals allows for precision time stamping of digitized data.

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.
Miscellaneous
| Parameter | Minimum | Typical | Maximum | Units |
|---|---|---|---|---|
| Analog Input | 0 dBm | +3 dBm | dBm | |
| Analog 3dB Passband | 5 | 270 | MHz | |
| External Clock Input1 (AC-coupled) | 250 | 500 | 1100 | mV p-p |
| External Ref.1 (AC-coupled) | 250 | 500 | 1100 | mV p-p |
| Analog Input Impedance | 50 | Ohms | ||
| Sample Clock | 402 | 250 | MHz |
Notes:
- Operation using external reference of 10MHz replaces the external clock input. Sample clock is then generated from the 10MHz reference.
- Operation below 40 MSamp/sec is possible by over-sampling at 40MHz or above and then decimating the data.
