2.3.1. Bill of Materials: Si2493/57/34/15/04 Chipset
Notes:
1. In STB applications, C40, C41, and Y1 can be removed by using the 27 MHz clock input feature.
2. Several diode bridge configurations are acceptable. For example, a single DF04S or four 1N4004 diodes may be used.
3. To decrease emissions, R15 and R16 may be populated with a BLM21AG601S or equivalent. R12 and R13 may be
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. 50 ppm initial accuracy crystals typically satisfy this
requirement.
