The Connor-Winfield
VSPML634C is a 3.3V Voltage
Controlled SAW Oscillator
(VCSO) with Differential LVPECL
outputs and a CMOS
Enable/Disable input. The
VSPML634C is designed for use
with PLL systems in SONET/SDH
systems requiring low jitter and
tight stability. No uses of
multiplication schemes are used
in this oscillator design.

Frequency stability vs. temperature. Control voltage (Vc) = 1.65 Vdc.
Referenced to Fo @ 25°C. Positive Slope.
Absolute pull range (APR) is the minimum guaranteed pull range of the VCXO under all conditions for ten year lifetime
operation. The APR is referenced to Fo.
With no connect on the enable / disable pin (pin 2) output is enabled. When oscillator is disabled the true output is in a
low state (Vol) and the complementary output is in the high state (VoH)
50 ohm termination into Vcc-2V or Thevein equivalent.
