Description

The M2053 is a VCSO (Voltage Controlled SAW Oscillator) based clock PLL designed for FEC clock ratio translation in 10Gb optical systems such as 10GbE 64b/66b. It supports both mapping and de-mapping of 64b/66b encoding and FEC (Forward Error Correction) clock multiplication ratios. The ratios are pin-selected from pre-programming look-up tables.
