The MAX9476 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 systems using T1, E1, T3, E3, and xDSL.
The MAX9476 features a phase-lock loop (PLL) that uses a voltage-controlled crystal oscillator (VCXO). The internal PLL phase locks the external crystal (35.328MHz) to the 8kHz input reference clock. In addition, this device generates a jitter-suppressed output that provides a better source for the reference clock relay.
The MAX9476 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. For using lower value external
crystals, refer to the MAX9486 data sheet.
