Product data sheet
9.2 Audio clock signals
9.3 Clock and real-time synchronization signals
The SAA7118 also synchronizes the audio clock and sampling rate to the video frame
rate, via a very slow PLL. This ensures that the multimedia capture and compression
processes always gather the same predefined number of samples per video frame.
An audio master clock AMCLK and two divided clocks ASCLK and ALRCLK are
generated:
The ratios are programmable; see
Table 26.
[1]
For the generation of the line-locked video (pixel) clock LLC, and of the frame-locked
audio serial bit clock, a crystal accurate frequency reference is required. An oscillator is
built-in for fundamental or third harmonic crystals. The supported crystal frequencies are
32.11 MHz or 24.576 MHz (defined during reset by strapping pin ALRCLK).
Alternatively pin XTALI can be driven from an external single-ended oscillator.
The crystal oscillation can be propagated as a clock to other ICs in the system via
pin XTOUT.
The Line-Locked Clock (LLC) is the double pixel clock of nominal 27 MHz. It is locked to
the selected video input, generating baseband video pixels according to “ITU
recommendation 601” . In order to support interfacing circuits, a direct pixel clock (LLC2) is
also provided.
