M2006-12
VCSO BASED FEC CLOCK PLL
Product Data Sheet
GENERAL DESCRIPTION
The M2006-12 is a VCSO (Voltage Controlled SAW
Oscillator) based clock generator
PLL designed for clock frequency
translation and jitter attenuation.
Clock multiplication ratios (including
forward and inverse FEC) are
pin-selected from pre-programming
look-up tables. Includes Hitless
Switching and Phase Build-out to
enable SONET (GR-253) / SDH (G.813) MTIE and
TDEV compliance during reference clock reselection.
Hitless Switching (HS) engages when a 4ns or greater
clock phase change is detected.
This phase-change triggered implementation of HS is
not recommended when using an unstable reference
(more than 1ns jitter pk-to-pk) or when the resulting
phase detector frequency is less than 5MHz.
FEATURES
◆ Similar to the M2006-02 - and pin-compatible - but adds
Hitless Switching and Phase Build-out functions
◆ Includes APC pin for Phase Build-out function (for
absorption of the input phase change)
◆ Pin-selectable PLL divider ratios support forward and
inverse FEC ratio translation
◆ Supports input reference and VCSO frequencies up to
700MHz (Specify VCSO frequency at time of order)
◆ Low phase jitter < 0.5 ps rms typical
(12kHz to 20MHz or 50kHz to 80MHz)
◆ Commercial and Industrial temperature grades
◆ Single 3.3V power supply
◆ Small 9 x 9 mm SMT (surface mount) package
