DESCRIPTION
ABIN 38 O Antiblooming in ABS0 ABS1 ABS2 The levels on these three terminals determine which of the five antiblooming modes is selected: 21 I Mode ABS2 ABS1 ABS0 Operation 0 NC L L No ABG pulses 1 NC H L 2-MHz burst of ABG pulses 22 I 2 NC L H 1-MHz burst of ABG pulses 3 H H H 1-MHz continuous ABG pulses 23 I 4 L H H 2-MHz continuous ABG pulses Mode 1 is used for normal operation. BCP1 1 O Optical black clamp BCP2 2 O Optical black clamp BF 7 O Burst flag CBLK 6 O Composite blank CLK 50 O 3.34-MHz clock (factory-test point) CLK13M 47 O 13-MHz clock (connect to SN28838 color-subcarrier generator for color operation) CP1 3 O Clamp 1 (signal processing) CP2 4 O Clamp 2 (signal processing) CSYNC 5 O Composite sync Delay select for S1, S2, S3. When E/L is high, the three serial-transfer pulses occur early relative
