CMX605 Preliminary Information
Notes:
1. At 25 C, not including any current drawn from the CMX605 pins by external circuitry other than X1, C1
and C2.
2. At nominal signal frequencies and without skew..
3. Excluding XTAL/CLOCK pin.
4. At VDD = 5.0V, load resistance greater than 40kW , signal levels are proportional to VDD.
5. Frequency above 300Hz.
6. SPM has a soft rise and fall time of about 4.5ms. The level changes between VBIAS and 0dBm in 2dB
steps, 16 steps per rise and fall. When SPM is disabled, an extra 4.5ms falling tail end of signal should be
taken into consideration.
7. Referenced to DTMF tone of lower amplitude.
8. Bandwidth limited: 0 to 3.4kHz Gaussian Noise.
9. Timing for an external input to the XTAL/CLOCK pin.
10. Over the range VDD = 3.3V to 5.5V at TAMB = 25 C
