M928-02
VCSO BASED CLOCK GENERATOR
Prelimina r y Inf o r m ation
GENERAL DESCRIPTION
The M928-02 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. From the
M928-02-622.0800
, an output clock
frequency of 622.08MHz is
provided from eight LVPECL clock
output pairs. (Other frequencies are available; consult
factory.) The accuracy of the output frequency is
assured by the internal PLL that phase-locks the
internal VCSO to the reference input frequency
(19.44MHz for the M928-02-622.0800). 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 range 300MHz to 700MHz
(Consult factory for frequency availability)
◆ Eight identical LVPECL output pairs
◆ Jitter 0.7ps rms (@622.08MHz, over 12kHz-20MHz), typ.
◆ Ideal for OC-48/STM-16 clock reference
◆ Output-to-output skew < 100ps
◆ External XTAL or LVCMOS reference input
◆ Integrated SAW (surface acoustic wave) delay line
◆ Single 3.3V power supply
◆ Small 9 x 9 mm SMT (surface mount) package
