Manufacturer Part Number
ml7036
Description
Lineacoustic-selectable Echo
Manufacturer
Oki Semiconductor
Datasheet
SPECIAL NOTE
The specifications herein still includes target specifications, which might be altered without any prior information.
GENERAL DESCRIPTION
The ML7036-001 is an IC device consisted with built-in line/acoustic-selectable echo canceller and two channels
of PCM codec’s for simple interfaces to a speaker and from a microphone (acoustic side) and for handset analogue
voice interface (line side).
For the line interface, additionally -law PCM or 16-bit linear PCM digital interface is reserved for cellular phones
with digital audio interface.
Equipped with gain and mute controls for data transmission and reception as well as an Auto Gain Control function
which simplify your level diagram design, and transfer clock and sync clock generators for digital communication,
ideally suited for a hands-free.
FEATURES
• Single 3 V Power Supply Operation (2.7 ~ 3.6V)
• Built-in line/acoustic-selectable 1-channel echo canceller
• 2-channels built-in CODEC’s
• AGC’s (Auto Gain Controllers) both on transmit and receive
• Built-in analog input gain amp stage (max. gain = 30 dB)
• Analog output configuration : Push-pull drive (can drive a 1.2 k
• Digital interface coding formats
• Digital interface sync formats
• Digital interface bit sequence
• Built-in digital transmission clock generators
• Digital transmission rate
• Fixed digital interface sync clock (SYNC) enables automatic power-down
• Master clock frequency
• Low power consumption
• Transmit/receive mute function, transmit/receive selectable gain setting
• Control by both the serial microcomputer interface and parallel port is possible
