Input crystal or clock frequency of 25 MHz - Preset divide ratios for 156.25 MHz, 33.33 MHz,100 MHz, and 125 MHz
- Choice of LVPECL or LVDS output format
- Integrated loop filter
- 6 copies of reference clock output
- Rates configured via strapping pins
- Space saving 6 mm × 6 mm 40-lead LFCSP
- 0.48 W power dissipation (LVDS operation)
- See data sheet for additional features
The PLL section consists of a low noise phase frequency detector (PFD), a precision charge pump (CP), a low phase noise voltage controlled oscillator (VCO), and a preprogrammed feedback divider and output divider. By connecting an external crystal or reference clock to the REFCLK pin, frequencies up to 156.25 MHz can be locked to the input reference.
Each output divider and feedback divider ratio is prepro-grammed for the required output rates. No external loop filter components are required, thus conserving valuable design time and board space.
The AD9571 is available in a 40-lead 6 mm × 6 mm lead frame chip scale package and can be operated from a single 3.3 V supply. The operating temperature range is −40°C to +85°C.
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
