Remove both screws using a coin, etc. and, after removing, retain them together with the Warranty card and other documents. When the unit is to be trans- ported again, be sure replace the two screws to their origi- nal position. ATTACHING THE TRANSPORTATION SCREWS 1. Turn the power ON without loading disc. 2.

CIRCUIT DESCRIPTION o Input signal description (ex, CX23035) 1) Digiul audio data This LSI uses 16-bit serial digital audio data' and the data bits are arranged from backward with respect to LRCK. As the period of clock BCK is equal to the data bit rate, more than 16 clocks are required for each word' For example, when the signal processor LSI connected is CX23035, which is a CD signal processor, LRCK is "H" during the L-ch audio data and "L" during the R-ch audio data, and the audio data is shifted in MSB-first mode at the fall of BCK. These Jactors can be set by the above- mentioned selector Pins. LRCK DATA BCK 3) Channel status data By connecting D2 (pin 26) with the write frame clock output terminal (wFcK) of the cD LSl, D3 (pin 25) with the subcode sync S0 + 51 output terminal (SCOR)' D4 lpin 24 with the subcode O output terminal (SUBO) and CRCK (pin 6) with the subcode O error flag terminal (CRCF), it becomes possible to read respectively the lD0' iot, COpv lNHlBlT and EMPHASIS information from SUBO and to set them on the specified positions of the C-bit data. However, when there is no terminal correspond- ing to cRCF, it shall be f ixed a|"H" ' 2) Master clock When a 1-sample/48-clock one-chip CD lC (CX23035) is used, a X'tal oscillator of 3 x 128Fs = 16'9344MH2 shall be connected across XTAL (pin 13) and EXTAL (pin 14). The internal circuitray of this LSI lC uses the 1/3 clock, which is 5.6MHz, as the master clock'whilethe CD uses the output from 192Fs (pin 12) as the master clock (3 x 12BFsl2 = 8.4672MH21. It is also possible to connect a 128Fs (5'6448MH2) X'tal oscillator across XTAL and EXTAL and to use it as the common master clock with the signal processor LSI. Fig.8-3 The category code (subcode bits 9 and 10) is input in DC via Cg (pin 16) and CiO (pin 5)' With the CD' the category code is (C9, C10) = (1' 0) so the bits are fixed at C9 = "H" and C10 = "L"' Note : D4 (SUBO) is read at the rise of D2 (WFCK)' latched and, when CRCF = "H"' loaded as the C'bit data at the fall of D3 (SCORI' lf CRCF = "L" ' the Previous value is held' With this LSl, it is also possible to input the chanel status data in parallel. In this case' lDO' lD1' COPY' EM- PHASIS and category code are input respectively to D4' D5, D6, D7 and C9 and C10 bv direct DC inputs' WFCK EXCKSBSO 18 SYNC. PATTERN Fig. 8-4
