Product details

Description

The BL1302A57/S is an A-law monolithic PCM Pin Assignment 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 H

Features

Complete CODEC and filtering system (COMBO) including: --- Transmit high-pass and low-pass filtering --- Receive low-pass filter with sinx/x correction --- Active RC noise filters --- A-law compatible COder and DECoder --- Internal precision voltage reference --- Serial I/O interface --- Internal auto-zero circuitry.
16 pin DIP or SOP.
Designed for ITU.
