LTE Standard Module Series The following figure shows the timing relationship in primary mode with 8 kHz PCM_SYNC and 2048 kHz PCM_CLK. Figure 8: Timing in Primary Mode In auxiliary mode, the data is sampled on the falling edge of the PCM_CLK and transmitted on the rising edge. The PCM_SYNC rising edge represents the MSB. In this mode, the PCM interface operates with a 256 kHz, 512 kHz, 1024 kHz or 2048 kHz PCM_CLK and an 8 kHz, 50 % duty cycle PCM_SYNC.
LTE Standard Module Series Clock and mode can be configured by AT command, and the default configuration is master mode using short frame synchronization format with 2048 kHz PCM_CLK and 8 kHz PCM_SYNC. In addition, EC21 series Mini PCIe’s firmware has integrated the configuration on some PCM codec’s application with I2C interface. See document [1] for details about AT+QDAI. The following figure shows a reference design of PCM interface with an external codec IC.

LTE Standard Module Series 6.8. Thermal Dissipation In order to achieve better performance of the module, it is recommended to comply with the following principles for thermal consideration: On customers’ PCB design, please keep placement of the PCI Express Mini Card away from heating sources. Do not place components on the PCB area where the module is mounted, in order to facilitate adding of heatsink.
LTE Standard Module Series 2. maximum temperature of the BB chip reaches or exceeds 105 °C, the module works normal but provides reduced performance (such as RF output power, data rate, etc.). When the maximum BB chip temperature reaches or exceeds 115 °C, the module will disconnect from the network, and it will recover to network connected state after the maximum temperature falls below 115 °C.
