1. ZTF Cabling for Archon Controller Stephen Kaye 2014-03-06

2. Cable Routing Changes Previous Cable Routing 8 Glenair 100 pin cables – Clock and Bias for 2 science CCDs 4 Samtec 98 pin twinax cables – Video signals for 4 science CCDs and 1 guider/focus CCD 4 Glenair 37 pin cables – Clock and Bias for 1 guider/focus CCD 2 Glenair 31 pin cables – Temperature, heater, and aux. signals New Cable Routing 4 Glenair 100 pin cables – Clock and Bias for 4 science CCDs 4 Samtec 98 pin twinax cables – Video signals for 4 science CCDs 2 Glenair 37 pin cables – Clock and Bias for 2 guider/focus CCD 2 Glenair 31 pin cables – Temperature, heater, and aux. signals 2 Samtec 26 pin twinax cables – Video signals for 2 G/F CCDs

3. Glenair 7580 – 100 pin TH, 4 CCDs Clock and Bias Signals Preamp Power 55.12mm x 11.94mm max ERF8-049 – 26 pairs SM, 4 CCDs 16 Video Signal Pairs, 8 Black Level Clamp Pairs, 64.87mm x 7.42mm Glenair 7580 – 37 pin TH, 2 CCD Guider/Focus Clock and Bias 37.72mm x 7.87mm Linear dimension of four 100 pins and one 37 pin connector is 258.2 mm with no spacing STA Connector Configuration March 5, 2014 Can we remove these unused overhangs? Glenair 7580 – 31 pin TH Auxiliary Signals Temperature and Heater ERF8-013 – 8 pairs SM, 2 CCDs 4 Video Signal Pairs, 4 Black Level Clamp Pairs, 64.87mm x 7.42mm

4. New Connector Configuration The edges with the guider/focus connectors need to be the edges where the guider/focus CCDs are located – Do we have orientation correct? VIB routing done by quarters with video signals orthogonal to clock/bias signals – Which way are streets running? Two G/F CCDs must have the same timing – all four are no longer independent – Maintains same chassis configuration for all boxes

5. Slot layout Science Controller Clock and Bias GMR7580 100 pins Video ERF8-049 Three blue connectors are the clock driver module board connectors (ERF8-013) Four grey connectors are the ADC module board connectors (ERF8- 013) One orange connector is HV Bias module board connector (ERF8-030) Purple connector is the LVDS custom board connector. Connector TBD. STA Personality Board STA Connectors ZTF Connectors

6. Slot layout Guider/Focus Controller Clock and Bias x2 GMR7580 37 pins Same boards as the science controller to keep controllers interchangeable Each connector controls two CCDs A pair (GMR7580 and ERF8-013) travels the left spider The other pair travels the right spider Recall personality card is removable from chassis. A single chassis can be exchanged between science CCDs and g/f CCDs STA Personality Board STA Connectors ZTF Connectors Video x2 ERF8-013

7. Custom LVDS Card Definition Sends LVDS signals – 16 pairs of LVDS Sends amplifier power – At least 4 pins of +5V @ 75 mA each – At least 4 pins of -5V @ 75 mA each Sends back bias voltage – At least 2 pins of -50V @ ? mA each – Adjustable by +/- 20% (?) Sends LVDS receiver power – At least 4 pins of +3.3V @ 20 mA each

8. Notes For each controller, we are utilizing a little over 2/3rds of the slots The guider/focus CCDs are paired
