M2006-02
VCSO BASED FEC CLOCK PLL
Product Data Sheet
GENERAL DESCRIPTION
The M2006-02 is a VCSO (Voltage Controlled SAW
Oscillator) based clock generator
PLL designed for clock frequency
translation and jitter attenuation.
The device supports both forward
and inverse FEC (Forward Error
Correction) clock multiplication
ratios. Multiplication ratios are
pin-selected from pre-programming look-up tables.
FEATURES
◆ Pin-selectable PLL divider ratios support forward and
inverse FEC ratio translation, including:
255/238 (OTU1) Mapping and 238/255 De-mapping
255/237 (OTU2) Mapping and 237/255 De-mapping
255/236 (OTU3) Mapping and 236/255 De-mapping
◆ Supports input reference and VCSO frequencies up to
700MHz, supports loop timing modes
(Specify VCSO frequency at time of order)
◆ Low phase jitter < 0.5 ps rms typical
(12kHz to 20MHz or 50kHz to 80MHz)
◆ Supports active switching between inverse-FEC and
non-FEC clock ratios (same VCSO center frequency)
◆ Ideal for complex ratio FEC ratio translation* and
for use with an unstable reference** (i.e., similar to the
M2006-12 - and pin-compatible - but without the Hitless
Switching and Phase Build-out functions)
◆ Commercial and Industrial temperature grades
◆ Single 3.3V power supply
◆ Small 9 x 9 mm SMT (surface mount) package

Note *: Complex ratio FEC ratio translation typically results in
low phase detector frequencies.
Note **: An unstable reference which results in phase detector
jitter beyond 2 ns under normal operating conditions
