I/Q SIGNAL ■■I/Q data details DD24-bit long I/Q data Data format: The I/Q data is composed of 3 parts: "I" signals, "Q" signals and Synchronous signals. Each data length is: "I" = 24 bits (3 Bytes), "Q" =24 bits (3 Bytes), Synchronous data=48 bits (6 Bytes). (The byte order is in the little-endian format.) I I I Q Q Q S S S S SS 3 bytes 3 bytes 6 bytes ••The synchronous data is to be followed by an "I" signal. ••I/Q data range is "-8387967 (0x800281) ~ +8387966 (0x7FFD7E)." I I I 3 bytes Q Q Q... 3 bytes The Synchronous data: ••Data length is 48 bits (6 bytes). ••The Synchronous data is composed of 6 bytes in total: 0x8000 (2 bytes), 0x8001 (2 bytes) and 0x8002 (2 bytes). 8000 2 bytes 8001 2 bytes 8002 2 bytes ••The Synchronous data is inserted into the I/Q data, at the following rate. Sampling rate 3.84 MHz 1.92 MHz 960 kHz 480 kHz 240 kHz Synchronous data appearance rate One Synchronous data in 8192 pairs of I and Q signals One Synchronous data in 4096 pairs of I and Q signals One Synchronous data in 2048 pairs of I and Q signals One Synchronous data in 1024 pairs of I and Q signals One Synchronous data in 512 pairs of I and Q signals DD16-bit long I/Q data Data format: The I/Q data is also composed of 3 parts: "I" signals, "Q" signals and Synchronous signals. Each data length is: "I" = 16 bits (2 Bytes), "Q" =16 bits (2 Bytes), Synchronous data=32 bits (4 Bytes). (The byte order is in the little-endian format.)
