Operating Characteristics Notes:

1. Not including any current drawn from the MX604 pins by external circuitry other than X1, C1 and C2.

2. TXD, RXEQ and CLK inputs at VSS, M0 and M1 inputs at VDD.

3. Measured at the Rx Input Amplifier output (pin RXAMPOUT) for 1300Hz and VDD= 5.0V. The internal

threshold levels are proportional to VDD. To cater for other supply voltages or different signal level

ranges the voltage gain of the Rx Input Amplifier should be adjusted by selecting the appropriate

external components as described in section 5.1

4. Flat noise in 300-3400Hz band.

5. Relative to 775mVRMS with VDD= 5.0V for load resistance greater than 40k.

6. Open loop, small signal low frequency measurements.

7. Timing for an external input to the XTAL/CLOCK pin.
