SAA8200HL
Ensation Base integrated wireless audio baseband
7.3.1 Crystal oscillator
The crystal oscillator is a 50 MHz Pierce crystal oscillator with amplitude control. It can be
used in many applications e.g. as a digital reference for digital circuits, A/D and D/A
clocking, etc. It is a robust design and can be used across a large frequency range.
Features:
• On-chip biasing resistance
• Amplitude controlled
• Large frequency range: 1 MHz to 20 MHz
• Slave mode
• Power-down mode
• Bypass test mode.
7.3.2 Audio PLL
The audio PLL is a multi purpose PLL.
Features:
• Integrated PLL with on-chip Current Controlled Oscillator (CCO), no external
components for clock generation
• Input frequency range: 100 kHz to 150 MHz
• CCO output frequency: 275 MHz to 550 MHz
• Output frequency range: 4.3 MHz to 550 MHz
• Programmable pre-divider, feedback-divider and post-divider
• On the fly adjustment of the clock possible
• Positive edge locking
• Frequency limiter to avoid hang-up of the PLL
• Lock detector
• Power-down mode
• Possibility to bypass whole PLL, the post-divider or the pre-divider
• Possibility to disable the output clock
• Skew mode
• Free running mode
• Scan mode
• Maximum peak cycle-to-cycle output jitter = 200 ps.
