Improved Performance
5x7mm
TB / TVB Model Series
TCXO / VCTCXO
Description:
Connor-Winfield's TBxxx
and TVBxxx series
TV
B5
0
10 4 12
are 5x7mm TCXO and
.0
MH 42
Z
VCTCXO products with
exceptional frequency
stability and low phase
noise.
Similar to our Txxx
/ TVxxx series, these devices are quieter,
smoother over temperature and are available at
higher frequencies.
Using the latest analog TCXO technology,
the TBxxx and TVBxxx series have improved
phase noise and frequency stability
performance and are available in 4-pad or 10-
pad surface mount footprints.
These products are designed for
such applications as IEEE 1588 PTP and
Synchronous Ethernet.

RoHS compliant lead free. See soldering profile on page 6.
Initial calibration @ 25°C. ±2°C, for VCTCXO's Vc = 1.65V. Specifications at time of shipment
Frequency stability vs. change in temperature. [±(Fmax-Fmin)/(2*Fo]). For VCTCXO, Vc = 1.65Vdc
Inclusive of frequency stability, supply voltage change (±1%), aging, for 24 hours. Per STRATUM 3 GR-1244-CORE.
Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C
Two consecutive solder reflows after 1 hour recovery @ 25°C.
Frequency drift over 1 year @ 25°C.
Inclusive of calibration @ 25°C, frequency vs. change in temperature, change in supply voltage (±5%), load change (±5%), reflow
soldering process and 20 years aging.
8. For Fo<40MHz, BW=12kHz to Fo/2, for Fo>40MHz, BW=12kHz to 20MHz
9. Ouput is active with Pad 8 not connected. Leave Pad 8 open if disable function is not required. When disabled, output stage is off
but oscillator and compensation circuits are still powered (current consumption <2 mA)
10. Attention: To achieve optimal frequency stability, and in some cases to meet the specification stated on this data sheet, it is
required that the circuit connected to this TCXO output must have the equivalent input capacitance that is specified by the
nominal load capacitance. Deviations from the nominal load capacitance will have a graduated effect on the stability of
approximately 20 ppb per pF load difference.
11. Load components are required for proper operation of the device.
12. Output is AC coupled.
