Notes:
1. In applications that do not require caller ID, C11, R20, and R21 can be removed.
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
used.
4. Three parallel 619 Ω, 1/4 W, resistors may be used instead of R1.
5. Three parallel 732 Ω, 1/4 W, resistors may be used instead of R2.
6. The package size on R7 and R8 must be at least 0805.
7. Murata BLM18AG601SN1 may be substituted for R15–R16 (0 Ω) to decrease emissions.
8. 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.
9. Two series Zener diodes may be used instead of Z1.
