Overview
Description
The M106x Voltage Controlled SAW Oscillator (VCSO) based clock PLLs are designed for Forward Error Correction (FEC) clock ratio translation in 10Gb optical systems such as OC-192 or 10GbE. They support 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 62.5 to 175 MHz
- Low phase jitter < 0.5 ps RMS typical (12kHz to 20MHz or 50kHz to 80MHz)
- Pin-selectable PLL divider ratios support FEC ratios
- M1060/65: OTU1 (255/238) and OTU2 (255/237) mapping
- M1061/66: OTU1 (238/255) or OTU2 (237/255) de-mapping
- M1062/67: OTU1 (238/255) and OTU2 (237/255) de-mapping
- LVPECL clock output
- 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 SMT (surface mount) package
