M624 VCSO
Preliminary Specifications
M624
622MHz Voltage Controlled SAW Oscillator
DESCRIPTION
The Surface Mount Technology (SMT) Voltage
Controlled SAW Oscillator (VCSO) is specifically
designed for high speed SONET/SDH OC-192 and
OC-768 applications.
This SMT VCSO is SAW-based and offers excellent
phase noise performance and spectral purity, while
requiring a low supply voltage (+3.3Vdc).
An extremely linear tuning range makes the SMT
VCSO especially suited for Phase-Locked Loop (PLL)
applications, which are extensively used in timing
circuits and clock and data recovery in fiber-linked
data systems.
The SMT VCSO’s small size and minimal power
requirements make it ideal for the miniaturization
applications that are emerging, without sacrificing
performance.
