Not to be confused with the QIE card.
The primary ADC chip of the CMS HCAL detector.
The QIE outputs the following 2 bytes of data every time slice (BX):
- CID - 2 bits, identifies the capacitor that integrated the input current
- ADC - 8 bits (6 bits for mantissa, 2 bits for range), identifies the charge value of the integrated input current
- TDC - 6 bits, identifies the leading edge of the input current
- teststand - The teststand class
- tests.acceptance - The acceptance test class
