To all our customers
Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

ALC (Automatic Level Control)
ALC is the input decay rate variable system. It has internal variable resistors of pin 8 (pin 23) by REC
signal that is inputted to pin 7 (pin 24).
Pin 17 is detector pin.
The signal input pin is pin 7 (pin 24). Resistor R1, R2 and capacitor C2, external components, for the input
circuit are commended as figure 4. There are requested to use value of the block diagram figure for
performance maintenance of S/N, T.H.D. etc.
Figure 5 shows the relation with R1 and C1 front input point and RECOUT.
ALC operation level acts for the center of +4.5 dB to standard level (453 mVrms).
Then, adopted maximum value circuit, ALC is operated by a large channel of signal.
RECOUT
ALC ON/OFF can switch it by pin 11. Please do ALC ON, after it does for one time ALC OFF inevitably,
for ALC time to start usefully, in order to reset ALC circuit.
