TABLE 2.0
NOTE
The Connor-Winfield VSPM634D
is a 5.0V Voltage Controlled SAW
Oscillator (VCSO) with
Differential PECL outputs and a
CMOS Enable/Disable input. The
VSPM634D is designed for use
with PLL systems in SONET/SDH
systems requiring low jitter and
tight stability. No multiplication
schemes are used in this

Frequency stability vs. temperature. Control voltage (Vc) = 2.50 Vdc.
Referenced to Fo @ 25°C. Positive Slope.
Absolute pull range (APR) is the minimum guarant eed 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. W hen oscillator is disabled the true output is in a
low state (Vol) and the complementary output is in the high stat e (VoH)
50 ohm termination into Vcc-2V or Thevein equivalent.
