M2006-12 - VCSO BASED FEC CLOCK PLL / HITLESS SWITCHING OPTION

Description

The M2006-02 and -12 are VCSO (Voltage Controlled SAW Oscillator) based clock generator PLLs designed for clock frequency translation and jitter attenuation.

Features

  • Pin-selectable PLL divider ratios support forward and inverse FEC ratio translation, including:.
  • 255/238 (OTU1) Mapping and 238/255 De-mapping.
  • 255/237 (OTU2) Mapping and 237/255 De-mapping.

Integrated Circuit Systems, Inc. Product Brief M2006-02/-12 VCSO BASED FEC CLOCK PLL / HITLESS SWITCHING OPTION PIN ASSIGNMENT (9 x 9 mm SMT) FIN_SEL1 GND FIN_SEL0 FEC_SEL0 FEC_SEL1 FEC_SEL2 FEC_SEL3 VCC DNC DNC DNC NC or APC DIF_REF0 nDIF_REF0 REF_SEL DIF_REF1 nDIF_REF1 VCC GENERAL DESCRIPTION The M2006-02 and -12 are VCSO (Voltage Controlled SAW Oscillator) based clock generator PLLs designed for clock frequency translation and jitter attenuation. They support both forward and inverse FEC (Forward Error Correction) clock multiplication ratios, which are pin-selected from pre-programming look-up tables. The M2006-12 adds Hitless Switching and Phase Build-out to enable SONET (GR-253) / SDH (G.813) MTIE and TDEV compliance during reference clock reselection.
