TZA1045 Photodiode And Amplifier IC For CD And DVD Applications

The TZA1045 is a single optical pick-up IC for read/write systems and is suitable for CD and DVD applications. The device contains eight RF Amplifiers for the central and satellite Diodes and one differential RF Amplifier (RFP and RFN) which handles the sum of the four A, B, C, and D central Diode signals. Programming the gain is a very versatile way to optimize interfacing between the TZA1045 and the pre-amplifier. The gain CAN be programmed for CD or DVD media with the gain Switch CD/DVD. The H/L Switch CAN be used for CD-R or CD-RW discs. Gain Switch R/W is used to reduce the gain during writing. During writing, the high peak signals for the central and satellite segments are clamped internally and the output currents of the A, B, C, D, E, F, G, and H segments are reduced to almost zero (fold back) to minimize the power consumption. All outputs are current outputs that CAN supply a maximum of 8 mA. In CD-R writing mode, the clipping level of the output currents is between 5 and 8 mA. The SSOP16T package has a low spread on the z tolerance. The z tolerance is measured between the Diodes (chip surface) and the bottom of the leads. The Diodes have an offset of 54 um in the ,y, direction with respect to the leadframe centre and a tolerance of +-50 um in both ,x, and ,y, directions. The Diodes are placed under an angle of 45Deg +-1Deg with respect to the leadframe of the module.
