M2085 - VCSO FEC PLL WITH AUTOSWITCH FOR SONET/OTN
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.
They support FEC (Forward Error Correction) clock multiplication ratios, both forward (mapping) and inverse (de-mapp
