Power Supply
Low-Speed Parallel Data
Low-Speed Parallel Data (LSB)
Ground
Low-Speed Clock Output (77.76MHz). A divide-by-32 version
of the CLKI± input clock.
Frame Detect Output. Set HIGH when frame detect occurs.
Power Supply
Parity Output
Tri-State Inputs. Allows tri-stating of all output signals. Used for
test only. Should be tied to VEE during normal operation.
Parity Select Input. HIGH for even; LOW for odd.
Tri-State Inputs. Allow tri-stating of all output signals. Used for
test only. Should be tied to VEE during normal operation.
