• Manufacturer Part Number: MC44S803EP
• Description: Low Power CMOS Broadband Tuner
• Manufacturer: FREESCALE [Freescale Semiconductor, Inc]

a crystal meeting the crystal specifications shown in Table 40.
Of course the frequency tolerance will be application specific.
Look at the specification for the demodulator that you intend
to use with the tuner for frequency tolerance that it needs to
capture signal. Internal load capacitance is 10 pF, typical PC
board stray capacitance is 3.0 or 4.0 pF.
