... An HF current amplifier is implemented to detect the actual HF data signal. The Fast Track Count (FTC) amplifier generates a radial error signal to allow fast track counting. TZA1020A (AEGER2A) is similar to the TZA1020, except for non-clamped MIRN, which allows operation with IGUANA. CONDITIONS C ...

... The fast track count circuit generates a Radial Error (RE) signal for fast track counting. A gain switch compensates for difference in CD-R and CD-RW disc reflection. 7.7 Spot position measurement To allow alignment of photo diodes via the TZA1020, a number of linear combinations of input currents can be realized (MEAS1 and MEAS2). Selection of the actual combination is performed by the I 7 Product specifi ...

... I C-BUS PROTOCOL 8.1 Addressing and data bytes Full control of the TZA1020 is accomplished via the 2-wire I 2 accordance with the I C-bus fast-mode specification. For programming the device (write mode) eight data byte registers are available/addressable via eight subaddresses. Automatic subaddress incrementing enables the writing of successive data bytes in one transmission. During power-on, ...
