M2085 - VCSO FEC PLL WITH AUTOSWITCH FOR SONET/OTN

Download the M2085 datasheet PDF. This datasheet also covers the M20 variant, as both devices belong to the same vcso fec pll with autoswitch for sonet/otn family and are provided as variant models within a single manufacturer datasheet.

General Description

The M2080/81/82 and M2085/86/87 are VCSO (Voltage Controlled SAW Oscillator) based clock PLLs designed for FEC clock ratio translation in 10Gb optical systems such as OC-192 or 10GbE.

Key Features

  • Integrated SAW delay line; Output of 15 to 700 MHz.
  • Low phase jitter < 0.5 ps rms typical (12kHz to 20MHz or 50kHz to 80MHz).
  • LVPECL clock output (CML and LVDS options available).
  • Pin-selectable PLL divider ratios support FEC ratios.
  • M2080/85: OTU1 (255/238) and OTU2 (255/237) Mapping.
  • M2081/86: OTU1 (238/255) or OTU2 (237/255) De-mapping.
  • M2082/87: OTU1 (238/255) and OTU2 (237/255) De-mapping 28 29 30 31 32 33 34 35 36 M2080 Series (Top Vi.

They support FEC (Forward Error Correction) clock multiplication ratios, both forward (mapping) and inverse (de-mapping). Multiplication ratios are pin-selected from pre-programming look-up tables. FEATURES ◆ Integrated SAW delay line; Output of 15 to 700 MHz * ◆ Low phase jitter < 0.
