Embedded Modem Modules (EMM) built using the 2430RD design information have been successfully tested for compliance to EN60950, EN55024, and TBR-21 to satisfy the requirements of many European applications. (Please refer to the 2420RD Designer’s Guide for North American applications.) • • • • • • The 2430RD modem module design produces a printed circuit board with dimensions of 1.45” x 1.85” (3.68cm x 4.70cm) that can be socketed or soldered into the host system controller board. OEMs can use the 2430RD to build embedded modem modules for a variety of low data rate applications such as a set top box billing modem or any remote data acquisition application. The 2430RD design supports a standard V.24 interface to the host Data Terminal Equipment (DTE).

Modem Description The 2430RD reference design architecture is based on a highly integrated TDK 73M2901 chip that includes the CPU, AFE, MAC, ROM, RAM, and UART that is controlled through the TDK “AT" like command set. Detailed information and support on this chipset can be found on the TDK Semiconductor website at www.tsc.tdk.com. The 2430RD EMM design also utilizes a compact Clare CPC5610 optical silicon DAA configured for TBR-21 European PSTN operation. The Clare CPC5610 DAA eliminates the on-board coupling transformer along with much of the regulatory agency certification risk usually associated with dial up modems. EMMs built using the 2430RD material have been successfully tested to be fully compliant with EN60950, EN55024, and TBR-21standards for interface to the telephone network. Clare’s 2430RD EMM reference design is capable of being powered by either a single +3.3V or +5.0V power supply source and supports automatic standby idle mode. EMMs based upon the 2430RD will also accept a request to power down from the DTE via hardware control. Low Power Mode The 2430RD design supports a low power mode. If the low power standby option is enabled the modem module will go into a power saving mode when idle. The on board oscillator will be running, clocks will be supplied to the modem’s UART, timers and interrupt blocks; but no clocks will be supplied to the CPU. Instruction processing and activity on the internal busses is halted. Normal operation is resumed when an Asynchronous and Synchronous Serial Data Interface The serial data interface consists of the TXD and RXD data paths (LSBit shifted in and out first, respectively); and the TXC and RXC serial clock outputs for synchronous data mode; CTS/RTS flow control; DCD, DSR and DTR. In synchronous mode, the data is passed at the bit rate (tolerance is +1%, -2.5%). Important TBR-21 Operating Note In order to be TBR-21 compliant, the following commands must be sent to the modem after Power Up Reset (POR): ATS99=0 ATS12=48 ATS13=32 Sets selection to TBR-21 Adjust DTMF levels to be compliant to TBR-21 These commands must be issued before any other command. Do not issue an AT&F or ATZ command after the S registers have been set otherwise the default settings will be invoked and the unit will not be TBR-21 compliant. Phone Line Interface The 2430RD design connects to the telephone line via the TIP and RING pair of signal lines located on J2 of the EMM. An additional EMI suppression and fuse network connected to the TIP and RING signal lines is recommended.

The TAS Emulators test loops are compatible with the testing standards from the EIA/TIA, NTT, and RITT and incorporate built-in setup files for common exchange and impairment conditions. Each TAS Emulator test loop has been assigned a percentage of how often it occurs in the real world PSTN network allowing the TAS Emulator to be set up to perform many types of tests. Each loop is given an EIA and TIA identifier, for example our second line tested is the TIA case I9A, LoopB=EIA1. A good source for further information can be found in TIA document TR30.3, or the TAS web site www.taskit.com by going to the support pull down menu and then to application notes. For modem designers, one of the more common tests performed is data throughput over the emulated PSTN test loops. Throughput testing checks the complete modem design by providing the initial connection speed information along with what the actual rate or throughput the data is transferred across the PSTN test loop. Therefore, TAS Emulator throughput test data provides information about the complete modem including the line interface or data access arrangement (DAA), the resolution of the codec, and most importantly the DSP’s ability to compress and error correct the data. Data presented in the chart below represents the results Clare obtained form EMM built with the 2430RD design material. The actual raw test data can be found on the following page. 2430RD EMM Throughput Over TIA Test Loops 3000 2000 1500 1000 500 TIA Loop Number Page 11 of 13 www.clare.com 81 77 73 69 65 61 57 53 49 45
