Design Features
Selecting passive components for PLLs By Aaron Schultz, Quake Technologies
PLLs in SERDES circuits typically require external resistors and capacitors. Other PLLs, such as cleanup circuits with high-Q VCXOs, also use external components. Theory and practical experimentation combine to enable you to optimize these components' values, minimizing jitter.
Designing a NEBS-compliant power system By T DeLurio and J Ng, Summit Microelectronics, and M Guz, Power-One
A complete power system guarantees the problem-free operation of telecommunications equipment and that equipment's compliance with applicable standards. Designing the complete power system requires expertise in areas beyond power conversion.
