Notes:

1. C52 and C53 should not be populated with the Si2493 16-pin package option.

2. Several diode bridge configurations are acceptable. For example, a single DF04S or four 1N4004 diodes may be used.

3. Murata BLM18AG601SN1 may be substituted for R15–R16 (0

) to decrease emissions.

4. 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.
