Notes:
1.
In STB applications, C40, C41, and Y1 can be removed when using the 27 MHz clock input feature. See "Clock
Generation Subsystem" on page 20.
2.
Several diode bridge configurations are acceptable. For example, a single DF04S or four 1N4004 diodes may be
used.
3.
56
Ω
, 1/16 W, 1% resistor may be substituted for R12–R13 (0
Ω
) to decrease emissions.
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
accuracy, 5-year aging, 0 to 70 °C, and capacitive loading. 50 ppm initial accuracy crystals typically satisfy this
requirement.
