UMC L40LP 40nm Spread Spectrum PLL - 75MHz-375MHz
The Spread Spectrum PLL is designed to multiply an input clock by a fixed-point number between 92 and 184 with frequency spreading capability suitable for PC and consumer electronics applications that require low EMI. It does not provide any deskew functionality. It contains a 1-64 divider at the reference clock input, a 1-256 or larger integer divider and a 1-256 or larger fractional divider in the internal feedback path, with as many as 4 bits of precise fractional-N control, and a 1-8 divider at the output. It can generate precise and adjustable frequency spreading depths (1.5% typical and up to around 10%) and rates (30KHz typical). The outputs are 50% duty cycle for all output divider values.
特色
- Designed for PC, networking, and consumer-electronics applications where spread-spectrum clock sources are required to satisfy FCC requirements for peak RF spectral emissions.
- Spreading rate and spreading depth are precisely adjustable to allow the designer to dial-in the desired characteristics.
- 15-bit fractional-N feedback divider with 4 bits of precise control.
- Available with multi-phase outputs.
