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

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 layoutScience Controller STA Connectors • 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 ZTF Connectors Video ERF8-049 Clock and Bias GMR7580 100 pins

6. Slot layoutGuider/Focus Controller STA Connectors • 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 ZTF Connectors Video x2 ERF8-013 Clock and Bias x2 GMR7580 37 pins

7. Custom LVDS CardDefinition • 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
