Base-band in-phase input: positive terminal. Internal 5 k Ω to VCM generator. If VCM is BBI_P 27 I internally generated (PWD_BB_VCM = 0), external AC coupling caps and 100- Ω differential termination to BBI_N is required. Base-band in-phase input: negative terminal. Internal 5 k Ω to VCM generator. If VCM is BBI_N 28 I internally generated (PWD_BB_VCM = 0), external AC coupling caps and 100- Ω differential termination to BBI_P is required. Base-band in-quadrature input: negative terminal. Internal 5 k Ω to VCM generator. If VCM is BBQ_N 9 I internally generated (PWD_BB_VCM = 0), external AC coupling caps and 100- Ω differential termination to BBQ_P is required. Base-band in-quadrature input: positive terminal. Internal 5 k Ω to VCM generator. If VCM is BBQ_P 10 I internally generated (PWD_BB_VCM = 0), external AC coupling caps and 100- Ω differential termination to BBQ_N is required.
