Channel 1 receive data, receive clock, and receive symbol clock output pins.
During power-on, these output pins are at the output level of the clock recovery circuit selected
by a combination of SLS11 and SLS21 (described later). (Refer to Fig. 3.)
Channel 2 receive data, receive clock, and receive symbol clock output pins.
During power-on, these output pins are at the output level of the clock recovery circuit selected
by a combination of SLS12 and SLS22 (described later). (Refer to Fig. 3.)
Receiver slot select signal pins of Channel 1 (SLS11, SLS21) and Channel 2 (SLS12, SLS22).
The MSM7583 has four sets of clock recovery circuits and four AFC information storage
registers. One of the sets is selected according to a combination of the signals at these pins.
(Refer to Fig. 3.)
Channel 1 (SLS21, SLS11) = (0, 0): Slot 1, (0, 1): Slot 2
Channel 2 (SLS22, SLS12) = (0, 0): Slot 1, (0, 1): Slot 2
Receive data, receive clock, and receive symbol clock outputs.
These pins are at the output level selected by RXSEL (described below).
