digital linescan camera www.perkinelmer.com/opto input/output signal specifications (continued) enable (len). the camera clock (cclk) operates at either the mclk frequency or default camera frequency, and is synchronized to the analog video. the output of the cclk signal can be used to capture digital video data by a frame grabber or digitizer. the line enable (len) signal brackets the valid digital video. the signal becomes high one cclk period before the first valid pixel and goes low one cclk period before the last valid pixel. in all modes of operation on the lvds models, a single line delay is present due to the necessity of storing all video data into memory before the video is output. video gain the ld3500-series camera features an adjustable video gain. this allows users to amplify the video signals for individual application needs. photo response non- uniformity (prnu) remains linear with gain. cameralink models: gain levels are set by serial communication though the cameralink connector. gain can be set from 0 to 24.5 db in increments of 3.5 db. gain settings are not lost when the camera is powered down. parallel lvds (rs-644) models: gain levels are set by differential rs-644 gain control inputs on the camera connector. the gain levels can be set at 1, 2, 4 and 8x full-scale gain, allowing the user to easily configure the camera output to suit their application needs. gain settings are not held after power down; proper input signals must be given at start-up, and held throughout operation for gain settings to remain at desired levels. data and power connectors cameralink models: the communications connector on the ld3500-series camera is a 26-pin d-type male connector, common to all cameralink applications. this 26-pin connector contains all communications and controls needed for camera operation. power is provided to the ld3500 via a 6 pin, hirose hr10a circular jack. refer to table 1a for pinout of the communications and control connector. figure 2 provides pinout locations for this connector. figure 2. connector diagram 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 3m connector mdr26 position plug recommended cable: 3m14x26s2lb-xxx-olc 1 19 18 36 recommended cable: 3m10136-6000ec series parallel lvds connector: hirose hr10a mating part: hirose hr10a-7p-6s figure 3. power connector diagram 5 4 6 2 3 1 pdp-206.01b - 7/2002w page 3 pin signal 1 12-24vdc 2 12-24vdc 3 do not connect 4 do not connect 5 ground 6 ground table 2. power connector pinout note: the power connector and pinout are common to all cameralink and parallel lvds models
