Design Documentation for the Phase I HE, Calibration Module, Pin Diode PCB. The Pin Diodes read scintillator and SMA inputs and delivers the signal to the QIE11 channel ASICs through the Adapter Card (CMS doc 12742) within the Calibration Module (CMS doc 12746) located in slot J11 and J12 of the RBXs.

Notes and Changes:
Revision 3.March 2016
Modified from the original FNAL drawing number 000-EB-172296
to comply with QIE11 in the following ways:
* Provide individual signals for SIG and Ref
* Signal is not measured differential
* C1 (43pF) matches Terminal Capacitance at 5.5VDC reverse voltage (see p2 of S1223-01 datasheet)
* to be used with QIE11 Adapter card Rev2 mounted on QIE11 component side only (QIE11 bottom side mounting not checked)
* C3 added to remove pedestal noise
Note: Rev2 did not include C3 and was not released to CMS Doc DB.
