USB V.92/V.34/V.32bis Controllered Modem With CX20548 SmartDAA®
The modem cannot process AT commands and cannot detect and qualify ring signals. Connect to digital ground GND. Shaping includes both acoustic and line echo cancellation.
The modem can be awakened by the host sending a single any character typically followed by an AT command. The modem returns to normal mode upon receiving an AT command or receiving a qualified ring.
The conductive surface located on the bottom of the package and referred to as pin 17 is connected internally to device analog ground. Actions resulting from datashwet failures can include specification of minimum inter-call delay, extended delay between calls, and maximum numbers of retries before the number is permanently forbidden “blacklisted”. Speakerphone Mode Optional When using the optional CX Codec, the modem includes additional telephone handset, external microphone, and external speaker interfaces which support voice and full-duplex dx20548 FDSP operation.
Some AT commands are still valid but may operate differently than in data modem mode. Consult applicable reference design for exact component placement and values, and for layout guidelines. Ring detection frequency range. Upon receiving GSTN Cleardown from the remote modem in a non-error correcting mode, the modem cleanly terminates the call. All voltages referenced to ground VSS. See DC characteristics in Table The modem connects to host via a logical V.

Input signals should never exceed the voltage range from The CX Codec hardware interface signals are described in Table Conexant strives to produce quality documentation and welcomes your feedback.
The modem can speed sense data with mark or space parity and configures itself as follows: The modem provides a detection and negotiation technique for determining and establishing the best method of error correction between two modems. An unterminated input can acquire unpredictable voltages through coupling with stray capacitance and internal cross talk.
With PCM upstream enabled, data transmission supports sending data at line speeds up to 48 kbps. The host can separately control volume, muting, and AGC in microphone and speaker channels. Oa Electronic Inductor Output. Applies to types I and O unless otherwise indicated. AT commands control the codec bits-per-sample rate.
The CX current and power requirements are listed in Table Conexant products are not intended for use in medical, lifesaving or life sustaining applications. This mode can fallback to V. Connect to base of Q Connect to emitter of transistor Q The punch-style package is shown in Figureand the sawn-style package is shown in Figure Parameters are constantly adjusted to maintain stability with automatic fallback from full-duplex to pseudo-duplex operation.
The modem supports four low power modes: Calculated voltage is applied to this output to control off-hook and DC VI mask operation. Additional profiles may also be included. The modem can blind dial in the absence of a dial tone if enabled by the X0, X1, or X3 command.
In MNP 5, the modem increases its throughput by compressing data into tokens before transmitting it to the remote modem, and by decompressing encoded received data before sending it to the DTE.
