Overview
Description
The M2060/61/62 and M2065/66/67 are Voltage Controlled SAW Oscillator (VCSO) based clock PLLs designed for FEC clock ratio translation in 10Gb optical systems such as OC-192 or 10GbE. They support Forward Error Correction (FEC) 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 15MHz to 700MHz
- Low phase jitter < 0.5ps RMS typical (12kHz to 20MHz or 50kHz to 80MHz)
- Pin-selectable PLL divider ratios support FEC ratios
- M2060/65: OTU1 (255/238) and OTU2 (255/237) Mapping
- M2061/66: OTU1 (238/255) or OTU2 (237/255) De-mapping
- M2062/67: OTU1 (238/255) and OTU2 (237/255) De-mapping
- LVPECL clock output (CML and LVDS options available)
- Reference clock inputs support differential LVDS, LVPECL, as well as single-ended LVCMOS, LVTTL
- Loss of Lock (LOL) output pin
- Narrow bandwidth control input (NBW pin) to adjust loop bandwidth
- Hitless Switching (HS) options with or without Phase Build-out (PBO) are available to enable SONET (GR-253) /SDH (G.813) MTIE and TDEV compliance during reference clock reselection
- Single 3.3V power supply
- Small 9mm x 9mm surface mount package
