15 / 106 page  LLCC68 Data Sheet Rev. 1.0 DS.LLCC68.W.APP July 2019 15 of 106 Semtech www.semtech.com 3.4 Crystal Specifications Table 3-4: Crystal Specifications The reference frequency accuracy is defined by the complete system. The initial error, temperature drift, and ageing drift of both the transmitter and the receiver, over the lifetime of the product, should be taken into account in the calculations. 3.5 Electrical Specifications The electrical specifications are given with the following conditions unless otherwise specified: • VBAT_IO = VBAT = 3.3 V, all current consumptions are given for VBAT connected to VBAT_IO • Temperature = 25 °C • FXOSC = 32 MHz, with specified crystal • FRF = 434/490/868/915 MHz • All RF impedances matched • Transmit mode output power defined into 50 load impedance • FSK BER = 0.1%, 2-level FSK modulation without pre-filtering, BR = 4.8 kb/s, FDA = ± 5 kHz, BW_F = 20 kHz double-sided • LoRa® PER = 1%, packet 64 bytes, preamble 8 symbols, CR = 4/5, CRC on payload enabled, explicit header mode • RX/TX specifications given using default RX gain step and direct tie connection between Rx and Tx • Blocking immunity, ACR and co-channel rejection are given for a single tone (CW) interferer and referenced to sensitivity +3 dB • Optional TCXO and RF Switch power consumption always excluded Caution! Throughout this document, all receiver bandwidths are expressed as “double-sideband”. This is valid for LoRa® and FSK modulations.
