产品型号：BL1302A57A 产品名称：1302A57A编码***电路 封装形式：16LPDIP 产品代码：FI11PD01 国外同类：TP3057 BL1302A57A 编码***电路 General Description The BL1302A57 is an A-law monolithic PCM CODEC/filter which has the A/D and D/A conversion and a serial PCM interface. The device is fabricated using the advanced double-poly nwell CMOS process. It is pin compatible with TP3057. The encode portion of each device consists of an input gain adjust amplifier, an active RC pre-filter which eliminates very high frequency noise prior to entering a switched-capacitor band-pass filter that rejects signals below 200 Hz and above 3400 Hz. Also included are auto-zero circuitry and a companding coder which samples the filtered signal and encodes it in the companded A-law PCM format. The decode portion consists of an expanding decoder, which reconstructs the Pin Assignment Analog signal from the companded A-law code, a low-pass filter which corrects for the sinx/x response of the decoder output and rejects signals above 3400 Hz followed by a single-ended power amplifier capable of driving low impedance loads. The device requires two 1.536 MHz, 1.544 MHz or 2.048 MHz transmit and receive master clocks, which may be asynchronous; transmit and receive bit clocks , which may vary from 64 KHz to 2.048 MHz; and transmit and receive frame sync pulses. The timing of the frame sync pulses and PCM data is compatible with both industry standard formats.
