CXD1162P

The CXD1162P is a digital filter LSI with guardrupled sampling rate, developed for compact disc player.

There are some features as follows. First, 83 taps and 21 taps filters linked through cascade connections provide a guadrupled sampling digital filter. The second is built-in filters for 2 channels corresponding to L and R. Then is a varity of functions, including soft muting. At last, 83rd and 21st order filters have 2 modes of filter coefficients each, that enable the selection the filter characteristics most suitable for usage CXD1162P.

The following is about the CXD1162P absolute maximum ratings. The VDD (supply voltage) is from -0.5 to +6.5 V. The VI (input voltage) is from -0.5 to VDD+0.5 V. The PD (allowable power dissipation) is 550 mW (Ta=75). The TSTG (storage temperature) is from -55 to +150. Then is about the recommended operating conditions. The VDD (supply voltage) is from 4.5 to +5.5 V. The operating temperature is from -20 to +75. The fx (OSC frequency) is from 10 to 20 MHz.
