Pin Description
General Description
The MLX75012 is a triple wavelength photo detector IC (PDIC) with integrated amplifiers and control circuitry
for use in optical pick-up heads. Its 20 photo detectors are optimized for the detection of 405nm, 650nm, and
廬
780nm wavelength laser light used in HD-DVD, Blu-Ray , DVD, and CD applications and are arranged in two
3-beam photo detector arrays in the chip centre. The ten signal channels consist of four main-detector
channels (A, B, C, and D), four sub-detector channels (E, F, G, H), and two channels with balanced
differential output (RFP, RFN). The device features a test mode for PDIC adjustment, a sleep mode, and 8
selectable gain modes, which are controllable by digital- and tri-state logic. The integrated 49Bit one-time
programmable ROM allows parameter trimming of the MLX75012 for high product quality.
The MLX75012 is manufactured in a 0.6碌m BiCMOS-technology.
