M906-01
VCSO BASED GBE CLOCK GENERATOR
Product Data Sheet
GENERAL DESCRIPTION
The M906-01 is a PLL (Phase Locked Loop) based
clock generator that uses an
internal VCSO (Voltage Controlled
SAW Oscillator) to produce a very
low jitter output clock. It is ideal for
Gigabit Ethernet. The output clock
(frequency of 156.25 or 187.50MHz
for example) is provided from six
LVPECL clock output pairs. (Specify frequency at time
of order.) The accuracy of the output frequency is
assured by the internal PLL, which phase-locks the
internal VCSO to the reference input frequency (25 or
30
MHz for example). The input reference can either
be an external crystal, utilizing the internal crystal
oscillator, or a stable external clock source such as
a packaged crystal oscillator.
FEATURES
◆ Output clock frequency from 125MHz to 190MHz
(Consult factory for frequency availability)
◆ Six identical LVPECL output pairs
◆ Integrated SAW (surface acoustic wave) delay line
◆ Low jitter 0.7ps RMS (over 12kHz-20MHz)
◆ Ideal for Gigabit Ethernet clock reference
◆ Output-to-output skew < 100ps
◆ External XTAL or LVCMOS reference input
◆ Selectable external feed-through clock input
◆ STOP clock control (Logic 1 stops output clocks)
◆ Industrial temperature grade available
◆ Single 3.3V power supply
◆ Small 9 x 9 mm SMT (surface mount) package
◆ Pb-free design/construction on all 9 x 9 mm modules
