M2040
DESCRIPTION
The M2040 is a VCSO (Voltage Controlled SAW Oscillator) based clock generator PLL designed for clock protection, frequency translation and jitter attenuation in fault tolerant puting applications. It features dual differential inputs with two modes of input selection: manual and automatic upon clock failure. The clock multiplication ratios and output divider ratio are pin selectable. External loop ponents allow the tailoring of PLL loop response.
FEATURES
- Integrated SAW (surface acoustic wave) delay line; VCSO frequency of 400.00 or 533.3334 MHz;- outputs VCSO frequency or half; pin-configurable dividers
- Loss of Lock (LOL) indicator output
- Narrow Bandwidth control input (NBW Pin); Initialization (INIT) input overrides NBW at power-up
- Dual reference clock inputs support LVDS, LVPECL, LVCMOS, LVTTL
- Automatic (non-revertive) reference clock reselection upon clock failure; controlled PLL slew rate ensures normal system operation during reference reselection
