Bill of Materials: Si2457/34/15/04 Chipset
1. C52 and C53 should not be populated with the Si2457/34/15/04 16-pin package option.
2. In STB applications, C40, C41, and Y1 can be removed by using the 27 MHz clock input feature.
3. Several diode bridge configurations are acceptable. For example, a single DF04S or four 1N4004 diodes may be
4. Murata BLM21AG601SN1 may be substituted for R15–R16 (0 Ω) to decrease emissions.
5. To ensure compliance with ITU specifications, frequency tolerance must be less than 100 ppm including initial
