MAX9486
8kHz Reference Clock Synthesizer with Multiple Outputs at 35.328MHz
Clock Generator Optimized for xDSL CO Line Cards and Telecom Systems Requiring Low-Jitter Clock Outputs
Part Details
The MAX9486 low-cost, high-performance clock synthesizer with an 8kHz input reference clock provides six buffered LVTTL clock outputs at 35.328MHz. The clock synthesizer can be used to generate the clocks for T1, E1, T3, E3, and xDSL.
The MAX9486 has two phase-lock loops (PLLs). The first PLL uses a voltage-controlled crystal oscillator (VCXO). The second PLL is a frequency multiplier. With the two PLLs, the MAX9486 generates the output frequency at 35.328MHz. In addition, this device generates a jitter-suppressed 8kHz output that provides a better source for the reference clock relay.
The MAX9486 is available in a 24-pin TSSOP package and operates over the extended operating temperature range of -40°C to +85°C and a single +3V to +3.6V power-supply range.
Applications
- Telecom Equipment Using T1, E1, T3, E3, and ISDN Protocols
- xDSL Equipment in CO with Interface to the Telecom Protocols
