GCI Data Upstream
GCI data is serially transmitted to this pin for all 4 channels of IDT821064.
GCI Data Downstream
GCI data is received serially from this pin for all 4 channels of IDT821064.
Frame Sync.
FSC is an 8 kHz signal that identifies the beginning of Timeslot 0 in the GCI frame.
Data Clock.
The data clock is either 2.048 MHz or 4.096 MHz, which is determined automatically by IDT821064.
Time Slot Select
These pins are used to select one of the four time slot positions for Voice channels, Monitor and C/I channels.
Master Clock Input.
Master clock provides the clock for DSP. It can be 2.048 MHz or 4.096 MHz, which is determined automatically by
IDT821064. It is recommended to connect MCLK pin and DCL pin together.
Reset Input.
Forces the device to default state. Active low.
Chopper Clock Output.
Provides a programmable (2 -28 ms) output signal synchronous to MCLK.
Chopper Clock Output.
Provides a programmable 256 kHz, or 512 kHz or 16.384 MHz output signal synchronous to MCLK
Recommend to be connected to GNDD.
