Introduction 2.1 SCOPE The SC14CVMDECT SF is a programmable DECT module for voice and data services. The internal software stack receives commands and data from the application, for instance to set up a link to other modules. The application software can be implemented on the module itself or on an external host processor. The internal FLASH provides user space where custom applications can be located.

Functional description The UART hardware interface uses only TX/RX (see Figure 7). 4.1 UART INTERFACE The UART is normally used for API commands, but can also be used for software upgrades and debugging. The UART is a full duplex UART with frame type: 1 start bit, 8 data bits (LSB first), 1 stop bit, no parity, up to 115.2 kBd.

SC14CVMDECT SF Figure 13 Handset volume configuration 4.5 PP AUDIO MODES The PP audio handling consists of four audio states (see Figure 14). In these states the audio subsystem is configured for a certain audio mode: 4. Headset mode Selection between the modes is done via API calls; see document reference [2]. The Alert state is for tone playing and is entered automatically when tones are played using the API calls. The Alert state can originate from idle, earpiece, handsfree or headset mode. 1.
In Earpiece mode (Handset speaker) an artificial sidetone is generated. The level of the sidetone can be adjusted and setup in the VES through parameter fields Audio.Earp.Vol.Elementx, SideToneGain and Audio.Heads. Elementx.SideToneGain. In Earpiece mode it is possible to adjust the volume in the Earpiece via API calls. In Earpiece mode the PP audio is routed as shown in Figure 11. CVMDECT PP1 CVMDECT FP MIX 4CH PCM 4.5.
change accordingly. When the SC14CVMDECT SF is configured as a PP, the clock has the same accuracy as the FP clock. When the PP synchronises with a FP, the PP crystal is synchronized with the FP crystal and the PP clock will The accuracy is expected to be within 1 minute for up to 6 weeks without being locked to a FP.

checksum error is signalled back to the transmitter and the complete packet is retransmitted. The packet will be retransmitted until it is received correctly, or until the link is closed. When the PP goes in-range or out-of-range a signal is sent from the PP to the MMI software indicating whether the PP is in-lock or is out-of-lock with the FP. More transmitted packets will be received in the same order as they were transmitted. The application must handle flow control, if needed. 4.10.
SC14CVMDECT SF Figure 20 Handling product identities 4.11.2 Deregistration The different PCM interface modes and timings are shown in Figure 21 to 26. Refer to document [1] for detailed information. There are two ways of deregistering a PP from an FP: • Remote FP and PP deregistration The correct way to deregister a PP from an FP is to deregister it remotely in the FP.

SC14CVMDECT SF Re-certification of the SC14CVMDECT SF is required if at least one external antenna is added. On request, Dialog Semiconductor can provide a pre-certified PCB layout for an external antenna circuit. RF1 is also recommended to use and can be connected to the RF cable to be able to do the JPN DECT type approval test. 4.13.1 Internal antenna only The FAD function is not enabled if only the internal antenna is used. In this case pins RFP0, RFP0n, P0 and P0n must be left unconnected. 4.13.

Design guidelines 2. Earpiece mode 3. Handsfree mode (Speakerphone) This section describes the software and hardware considerations to be taken into account when designing the target application. 4. Headset mode Shifting between modes is done through the API. The SC14CVMDECT SF can be used standalone or next to an MCU that controls the module. In case the module is used standalone the application will be stored in its on-board Flash. In total 324 kB of Flash is available for this purpose.
• Microphone(s) • Headset microphone and speaker • Supply voltage • Speakerphone (signal grounds) • Battery charge Depending on the layout it may also be necessary to bypass a number of the audio signals listed above to avoid humming, noise from RF radiation and TDD noise with. It is also important to choose a microphone of appropriate quality with a high RF immunity (with built-in capacitor). • LED and buttons • Audio: • Headset • External PCM device.
Place the module at the edge of the main-board as shown in Figure 37. If the module has to be placed away from the edge of the main board, then avoid conducting areas in front of the antennas and make a cut-out in the main board underneath the antennas as shown in the figure. Keep a distance of at least 10 mm from the antenna elements to conducting objects and at least 5 mm to non-conducting objects. Keep solid ground on layer 2 out to the edges of the main board as shown in the figure.
