10 / 16 page ADMP621 Data Sheet When long wires are used to connect the codec to the ADMP621, a source termination resistor can be used on the clock output of the codec instead of a buffer to minimize signal overshoot or ringing. Match the value of this resistor to the characteristic impedance of the CLK trace on the PCB. Depending on the drive capability of the codec clock output, a buffer may still be needed, as shown in Figure 17. SLEEP MODE The microphone enters sleep mode when the clock frequency falls below 1 kHz. In this mode, the microphone data output is in a high impedance state. The current consumption in sleep mode is less than 5.5 µA. The ADMP621 enters sleep mode within 1 ms of the clock frequency falling below 1 kHz. The microphone wakes up from sleep mode and begins to output data 32,768 cycles after the clock becomes active. For a 3.072 MHz clock, the microphone starts to output data in 10.7 ms. For a 2.4 MHz clock, the microphone starts to output data in 13.7 ms. The wake-up time, as specified in Table 2, indicates the time from when the clock is enabled to when the ADMP621 outputs data within 3 dB of its settled sensitivity. START-UP TIME The start-up time of the ADMP621 from when the clock is active is the same as the wake-up time. The microphone starts up 32,768 cycles after the clock is active.
