Integrated Circuit Systems M1040
The M1040 is a VCSO (Voltage Controlled SAW Oscillator) based clock generator PLL designed for clock protection, frequency translation and jitter attenuation in OC-12/48 class optical networking systems. 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.| Part No. | M1040 |

GENERAL DESCRIPTION
This device provides two outputs. External loop components allow the tailoring of PLL loop response.FEATURES
● Integrated SAW (surface acoustic wave) delay line; low phase jitter of < 0.5ps rms, typical (12kHz to 20MHz)● Output frequencies of 62.5 to 175 MHz *; Two differential LVPECL outputs (CML, LVDS options available)
● 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
● AutoSwitch (AUTO pin) - automatic (non-revertive) reference clock reselection upon clock failure; Hitless Switching (HS), Phase Build-out (PBO) options enable SONET (GR-253)/SDH (G.813) MTIE/TDEV compliance
● Acknowledge pin (REF_ACK pin) indicates the actively selected reference input
● Industrial temperature available
● Single 3.3V power supply
● Small 9 x 9 mm SMT (surface mount) package 28 29 30 31 32 33 34 35 36 M1040 (Top View) 18 17 16 15...
