FREQUENCY TRANSLATION PLL WITH AUTOSWITCH

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 computing 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 components allow the tailoring of PLL loop response.

Integrated SAW surface acoustic wave delay line VCSO frequency of or 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

Acknowledge pin indicates the actively selected reference input

Dual differential LVPECL outputs

Low phase jitter of < 0.5ps rms, typical 12kHz to 20MHz or 50kHz to 80MHz

Industrial temperature available
