GENERAL DESCRIPTION
The TZA1046 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 TZA1046 and the preamplifier.
The gain can be programmed for CD or DVD media with
the gain switch CD/DVD.
The H/L switch is a three level switch that can be used to
adjust the gain for different dye and phase change media.
The third level (high-impedance state) invokes the
power-down mode for standby condition.
Gain switch R/W is used to reduce the gain during writing.
During CD-R writing with clipping, 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 folded back to reduce power consumption.
The output currents can be folded back to almost zero,
depending on the light power detected. CD-R writing can
also be done without clipping for applications where
averaging is used.
All outputs are current outputs that can supply a maximum
of 8 mA. In CD-R write clip mode, the clipping level of the
output currents is between 5 mA and 8 mA.
The HTSSON16T 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
µm the y direction with respect
to the leadframe centre and a tolerance of 50
µm in both
x- and y-directions.
In normal operation the satellite outputs F and H are
combined as one output FH and the satellite outputs
E and G are combined as one output EG. In normal mode
the ETST and HTST outputs are not used (high ohmic).
When pulling the R/W pin above the supply or is left open
the device comes into a testing mode where all four
separate satellite channels are directed to the outputs.
This mode is used for Optical Pick-up Unit (OPU)
alignment of the diodes where all satellite channels must
be available.
