High input enable receive mode, which disables the outputs of DP and DN, and the buffer goes into high-z state. O Differential Receiver Output (CMOS level digital output) When DP > DN, the output is “H”. When DP < DN, the output is “L”. When both DP and DN are “L”, the output is not guaranteed. this pin also outputs correctly regardless of the OEN input. O Schmitt Hysteresis Receiver Output for DP (D+) input (CMOS level digital output) When DP is high level, RSHP is high. When DP is low level, RSHP is low this pin also outputs correctly regardless of the OEN input. O Schmitt Hysteresis Receiver Output for DN (D-) input (CMOS level digital output) When DN is high level, RSHN is high. When DN is low level, RSHN is low this pin also outputs correctly regardless of the OEN input. I Suspend Mode Control Pin (CMOS level) High input forces the RDIFF output to low level, and the AK4170 goes into low power consumption mode regardless of OEN pin. P Ground Pin - Not Connected - Not Connected - Not Connected I Full Speed/Low Speed Control Input (CMOS digital input) Low input activates the AK4170 to Low Speed (1.5Mbps) mode. High input activates the AK4170 to Full Speed (12Mbps) mode. I/O...
