| [ASAHI KASEI] [AK4170] AK4170 Features n Ultra smooth output waveform n Support full speed(12Mbps) and low speed(1.5Mbps) n Single Power Supply 3.3 volts 10% n 16pin TSSOP package n Functionally compatible to Philips PDIUSBP11 n Support suspend mode USB Transceiver OEN FAST INP INN RDIFF SUS RSHP RSHN VDD VSS + - DP DN AK4170 Block Diagram nPin Layout NC OEN RDIFF RSHP RSHN SUS VSS NC 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VDD INN INP DP DN FAST NC NC -1- <1999/09> [ASAHI KASEI] [AK4170] Pin/Function No. 1 2 Signal Name NC OEN I/O I Description Not Connected Output Enable Pin (CMOS level digital input) Low input enables transmit data, it is that both INP and INN output onto DP and DN pins. High input enable receive mode, which disables the outputs of DP and DN, and the buffer goes into high-z state. 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. 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. 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. 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. Ground Pin Not Connected Not Connected Not Connected 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. Transmitter/Receiver Negative Data Output/Input Pin DN outputs the data of INN logic level when OEN is low DN disable the output, and goes to high-z state when OEN is high. Transmitter/Receiver Positive Data Output/Input Pin DP outputs the data of INP logic level when OEN is low DP disable the output, and goes to high-z state when OEN is high. Transmitter Positive Data Input Pin (CMOS digital input) When OEN is low, DP outputs INP logic level. When OEN is high, INP does not influence output pins. Transmitter Negative Data Input Pin (CMOS digital input) When OEN is low, DN outputs INN logic level. When OEN is high, INN does not influence output pins.
