Notes:
1.
Several diode bridge configurations are acceptable. For example, a single DF04S or four 1N4004 diodes may be used.
2.
Murata BLM21AG601SN1 may be substituted for R15–R16 (0
) to decrease emissions.
3.
To ensure compliance with ITU specifications, frequency tolerance must be less than 100 ppm including initial
accuracy, 5-year aging, 0 to 70 °C, and capacitive loading. For optimal V.92 PCM upstream performance, the
recommended crystal accuracy is ±25 ppm.
