73M1866B/73M1966B

MicroDAA™ with PCM Highway

DATA SHEET

April 2010

Simplifying System Integration™

DS_1x66B_001

DESCRIPTION

Through its PCM interface, the 73M1966B can

be connected to other PCM enabled devices

such as POTS codecs, ISDN codecs, E1/T1

framers, etc.

The 73M1866B and 73M1966B use the Teridian

patented Data Access Arrangement function

(MicroDAA^®) designed exclusively for Foreign-

Exchange-Office (FXO) in Voice-over-IP (VoIP)

applications. These devices provide much of the

circuitry required to connect PCM formatted

voice channels to a PSTN via a two-wire twisted

pair interface. The package options provide the

necessary functional programmability and

protection required for easy worldwide

Additional DAA functions supported by the

73M1x66B devices include a call progress

monitor, Caller ID Type I and II, ring detection,

pulse dialing, billing tone detection and polarity

reversal detection.

APPLICATIONS

homologation.

•

Computer Telephony

VOIP Equipment

PBX Systems

Internet Appliances

Voicemail Systems

POTS Termination Equipment

The family of devices consists of the 73M1866B

and the 73M1966B. The 73M1866B MicroDAA

is the world’s first single-package silicon Data

Access Arrangement (DAA). Suitable

applications for the 73M1866B and 73M1966B

devices include VoIP equipment that must

provide connectivity to the PSTN for purposes of

guaranteeing emergency service calling,

redundancy for supplementary connectivity for

voice, and maintenance services.

FEATURES

•

PCM highway data interface supporting both

slave and master modes

PCM highway interface supporting both E-1

and T-1

SPI control interface, with daisy chain

support for up to 16 devices

Designed to meet global DAA compliance

FCC, ETSI ES 203 021-2, JATE and other

PTT standards.

The 73M1966B device set consists of the

73M1906B Host-Side Device that provides digital

data, control interfaces and power to the

73M1916 Line-Side Device.

These devices are based on an innovative and

patented technology, which sets new standards

in reliability and cost. A small pulse transformer

forms a digital isolation barrier, transferring both

power and data to the PSTN line-side

components. This method results in reliable

operation in the presence of EMI and a tolerance

to line voltage variations by providing power to

the Line-Side Device across the barrier. The

devices also support the ability to provide up to

an additional +6 dB of analog gain to the line-

side transmit and +3 dB in the receive signal

paths. The device supports transmit and receive

digital gain ranging from –18 dB to +7.375 dB by

increments of 0.125 dB.

•

8 kHz and 16 kHz sample rates

16-bit linear mode

TX and RX gains adjustable in 0.125 dB

increments

•

μ-Law, A-law ITU-T Recommendation G.711

compliant compander operation

Automatic clock rate detection

Low power modes

Polarity Reversal detection

GPIO for user-configurable I/O ports

Call Progress Monitor

•

Isolation up to 6 kV

THD -80 dB

The digital side provides a PCM highway

interface with automatic clock rate detection.

With an 8-kHz sampling rate, the devices include

an ITU-T G.711 compliant codec with selectable

µ-law and A-law companding modes. The

devices also provide a 16-bit linear mode, which

is suitable for interfacing with wide band codecs,

as well as 16 kHz sampling rate. Device control

is performed over an SPI interface. The SPI

supports daisy chain operation.

5 V tolerant I/O on selected pins

3.0 V – 3.6 V operating voltage

Industrial temperature range (-40 °C to +85 °C)

5x5 mm 32-pin QFN or 20-pin TSSOP

packages

•

RoHS compliant (6/6) lead-free package
