GC6016 Minimum baseband bandwidth/sample rate

What is the GC6016's minimum supported baseband bandwidth or sample rate? 

Is the GC6016 suitable for Multi-Carrier GSM (MC-GSM) applications?

    Hello,

    The GC6016 DDUC can operate at a very low IQ rate <10khz.  The GC6016 Baseband Block has a minimum data clock of 50Mhz.  The GC6016 will gate the output serial, nibble, or byte data to meet the data frame rate.  The BB interface can have 3 modes, (3) 2wire serial, (2) nibble, and (1) byte.  Each BB interface can have a different IQ rate.

    Each DDUC can also support one resampler ratio and DDC or DUC at a time.

    The GC6016 can support the GSM 270.833e3 or 320e3 IQ rates.  Normally these are oversampled by 2x or 4x in the receive output.  In GC6016 could support a non DPD application for Tx and Rx for McGSM, given that 2 DDUCs are Tx and 2DDUCs are Rx, you can have 24 carriers in each direction.  The 24 carriers can be divided among 1, 2, or 4 antenna paths.

    In repeater applications, the Baseband rate or direct BBRxout to BBTxin needs to be evaluated for the desired latency.
