Description:

Connor-Winfield's TBxxx and TVBxxx series

are 5x7mm TCXO and VCTCXO products

with exceptional frequency stability and low

phase noise. Through the use of analog

temperature compensation, these products are

capable of holding Stratum 3 level temperature

stabilities of ±0.28 ppm over the commercial

and industrial temperature ranges. Available in

4-pad or 10-pad surface mount footprints.

These products are designed for

such applications as IEEE 1588 PTP or

Synchronous Ethernet.

Using the latest analog TCXO technology,

the TBxxx and TVBxxx series have improved

phase noise and frequency stability

performance.

Notes:

1. Initial calibration @ 25°C. ±2°C, for VCTCXO's Vc = 1.65V. Specifications at time of shipment after 48 hours of operation.

2. Frequency stability vs. change in temperature. [±(Fmax-Fmin)/(2*Fo]). For VCTCXO's - Vc -= 1.65V

3. Inclusive of frequency stability, supply voltage change (±1%), aging, for 24 hours. Per STRATUM 3 GR-1244-CORE.

4. Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C

5. Two consecutive solder reflows after 1 hour recovery @ 25°C.

6. Frequency drift over 1 year @ 25°C.

7. BW = 12 KHz to 20 MHz

8. Leave Pad 8 on the TB Series unconnected if enable / disable function is not required. When tri-stated, the output stage is

disabled but the oscillator and compensation circuit are still active (current consumption < 1 mA).

9. 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..
