Functional Description
The SM840001 provides a high performance and high
accuracy solution for a precision clock source at 106.25
or 212.50MHz derived from a low cost 26.5625MHz Xtal.
A single 12mA LVCMOS output is provided with tri state
capability, controlled via an external pin (OE).
The design of the SM840001 consumes very low power
in the PLL due to a patented technology in the VCO and
the associated dividers. The VCO range is ~3.2GHz to
3.5GHz providing high resolution and easy integer divide
ratios. Output Divider ratios are fixed at either ÷15 or ÷30
controlled via the FSEL pin, and the feedback divider
also fixed at ÷120. Duty Cycle is inherently improved and
guarantees tight control and stability on this critical
specification. The provides improved specifications for
Duty Cycle, Jitter, Phase Noise, Power Consumption,
and noise sensitivity. Additionally, the SM840001 will
operate at either 3.3V or 2.5V supplies.
