?11 cxa1100/cxa1101/cxa1102/cxa1163 when the ripple or noise component of v ee supply is not negligible small, the cr filter shown in fig. a-1 will be usefull. the operation voltage range are cxa1100 11.5 to 16v (5.75 to 8v) cxa1101 8.5 to 16v (4.25 to 8v) cxa1102 6.5 to 16v (3.25 to 8v) cxa1163 5.0 to 16v (2.5 to 8v) fig. a-1. the devices will satisfy the signal handling of 12db specified by dolby laboratories on above voltage range. 2) operation mode control the cxa1100 series provide fully electronic switching circuits. the functions are controlled by dc voltages of the two control pins of rec/pb (pin 12) and on/off (pin 5). the switching truth tables are shown in fig. a-2. v h and v l are defined as (a) single ended supply operation v cc 3 v h 3 2.5v 0.5v 3 v l 3 0v (b) split supply operation v cc 3 v h 3 v ee + 2.5v v ee + 0.5v 3 v l 3 v ee fig. a-2. it is desirable to provide cr time constant circuits at the mode control pins with time constant from 100msec to 1sec, which will reduce switching clicks effectively. 3) reference levels characteristics and specifications of the dolby noise reduction processor are defined as the levels and measured with reference to the dolby level. this particular level in these devices is ?0dbm (245mvrms), and is measured at the recording output (rec out) in the nr off mode. the reference levels of the recording input (rec in), play back input (pb in) and line output (line out) are defined the levels which provide the dolby level at the recording output in the nr off mode. the cxa1100 series has a common silicon die, and has different internal connection. the series provides four different line output levels for various applications. other reference levels, recording input level, playback input level and recording output level (= dolby level) are identical in all devices. the reference levels are as follows recording output level (= dolby level) ?0dbm (245mvrms) recording input level ?0dbm (24.5mvrms) play back input level ?0dbm (24.5mvrms) line output level cxa1100 0dbm (775mvrms) cxa1101 ?dbm (548mvrms) cxa1102 ?dbm (388mvrms) cxa1163 ?0dbm (245mvrms) 13 14 15 r1 43k 47 100 to 470f v ee cxa1100 series rec/pb function v h pb (decode) v l rec (encode) on/off function v h nr off v l nr on
?12 cxa1100/cxa1101/cxa1102/cxa1163 4) mpx filter termination and c 1 for vcc/2 (pin 4) the mpx (multiplex) filter termination method shown in fig. a-3 allows saving the coupling capacitors between the buffer amplifiers and mpx filters. however, the channel to channel separation and rec to pb crosstalk of low frequency signals will be degraded by the termination resistor rt. for example, 5k of r 1 will degrade the channel to channel separation to 50db. better separation can be obtained by increasing the capacitance of c 1 (pin 4) to 220f or 470f. the allowable minimum value of c 1 is 47f, and 100f is the standard recommended value. larger values of c 1 are generally desirable in order to improve the crosstalk and ripple rejection ratio. 5) application for dubbing cassette decks the cxa1100 series generates non decoded signal at the recoding output in the decode mode, and can simplify the structure of dubbing decks. see the sony' dolby b/c type ic (cx20187/cxa1097q or cx20188/cxa1098q) data sheet in detail. fig. a-3. switchable processor with single supply note 1) resistor and capacitor tolerances are 10% and 20% respectively unless otherwise specified. note 2) when resistors rt are connected to pin 4 for the mpx filter termination, increase the capacitances of c 1 and c 11 (c 21 ) to 470f and 4.7f respectively. 2 3 13 14 15 4 1 16 c1 470 r t r t mpx filter mpx filter mpx filter buffer mpx filter mpx filter mpx filter buffer c11 4.7 c21 4.7 line input line input cxa1100 series 3 4 5 6 7 8 10 11 12 14 15 1 c21 1 c22 1 nr on/off on off c24 4.7 line out c23 (10%) 0.68 c14 4.7 line out c13 (10%) 0.68 r1 (12 %) 43k c3 10 c12 1 c11 1 pb in (?0dbm) pb in (?0dbm) rec in (?0dbm) v cc 2 c2 100 c1 100 rec/pb r2 10k 13 rec pb 16 rec in (?0dbm) c25 4.7 rec out (?0dbm) c15 4.7 rec out * r t * r t 9 * *
