CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield VSPM634C
is a 5.0V Voltage Controlled SAW
Oscillator (VCSO) with
Differential PECL outputs and a
CMOS Enable/Disable input. The
VSPM634C is designed for use
with PLL systems in SONET/SDH
systems requiring low jitter and
tight stability. No multiplication
schemes are used in this
oscillator design.

Notes
1.0
Frequency stability vs. temperature. Control voltage (Vc) = 2.50 Vdc.
2.0
Referenced to Fo @ 25°C. Positive Slope.
3.0
Absolute pull range (APR) is the minimum guaranteed pul l range of the VCXO under all conditions for ten year lifetime
operation. The APR is referenced to Fo.
4.0
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 state (V oH)
5.0
50 ohm termination into Vcc -2V or Thevein equivalent.
