GENERAL DESCRIPTION
The AD9575 provides a highly integrated, dual output clock
generator function including an on-chip PLL core that is
optimized for network clocking. The integer-N PLL design is
based on the Analog Devices, Inc., proven portfolio of high
performance, low jitter frequency synthesizers to maximize line
card performance. Other applications with demanding phase
noise and jitter requirements also benefit from this part.
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 pin selectable feedback and
output dividers.
By connecting an external crystal, popular network output fre-
quencies can be locked to the input reference. The output divider
and feedback divider ratios are pin programmable for the required
output rates. No external loop filter components are required,
thus conserving valuable design time and board space.
The AD9575 is available in a 16-lead, 4.4 mm × 5.0 mm TSSOP
and can be operated from a single 3.3 V supply. The temperature
range is 40°C to +85°C.
