NKG3001B

NDK NKG3001B

VC-TCXO Oscillator DIP

12.8 MHz / 2.5ppm / +5V Single Supply

Here you are looking at the NKG3001B oscillator from NDK. They are through-hole package with 14 pin DIP footprint with 4 pins (14 = +5V, pin 7 = Gnd, Pin 8 = Output, Pin 1 = Control voltage) for connection.

Unlike TCXO oscillator, the VC-TCXO provides input pin for frequency tuning control voltage, resulting a more precise frequency which you can't achieve with the common TCXO. This can be implemented with a PLL on monitoring the output frequency. You may also skip this control circuitry and hook up a control voltage to pin 1 with just a resistor multi-turn trimmer and in this way, the NKG3001B works like the TCXO. This NKG3001B simply gives you more flexibility and precision than normal TCXO which you find in the market.

This specific frequency at 12.8MHz is interesting as it can be divided by binary counters to generate a 100kHz and further divided down by decades for an accurate 1Hz. Thus this can form a low-cost precision timebase, for clocks and test gear such as frequency counters. A typical example would be a GPSDO with phase-locked to a GPS unit which outputs 10KHz, eg. one by G4GNT here.

Its datasheet can't be located in the net but similar products in the market would gives up some ideas on the specification. This one on listed is completely brand new old stock, so bid with comfidence.

I do combine orders purchased within a 5-day period to save your shipping cost. You are welcome to email me for any other question.

Specification (similar VC-TCXO) of Toyocom TCO-977B for reference only:

Power Supply :
5V +/- 5%
Current Consumption :
about 2 mA
Output Level :
0.8Vp-p min (@ load = 10Kohm //10pF)
Stability vs Temp :
about +/- 2.5 ppm (-30C to +75C)
Stability vs Supply :
about +/- 0.3 ppm (@3V+/-5%)
Stability vs Load :

+/- 0.2ppm ( @ load = 10Kohm +/ 1kohm; 10pF +/-1pF)

Frequency Tolerance :
+/- 0.5 ppm max
Control Voltage :
+0.5V to +2.5V DC
Frequency Control Range :
+/- 9ppm (@+1.5V +/- 1V)
Aging:
+/-1 ppm max / year

Reference:
The datasheet can't be located from the net.

Price Reference:
DIP through-hole package oscillator is hard to find but similar product is priced at about GBP10 each in the internet .

What's a max bid?
Your max bid should be the highest amount you're willing to pay for an item.
We keep your max bid amount a secret from the seller and other bidders.
Max bidding example:
If a current bid is £20 and your max bid is £30, we bid £21 for you.
If no one else bids, you win and pay £21.
However, if someone else places a bid for £35, you will be out bid and the new highest bid on the auction will be £31. You will need to increase your max bid to more than £35 to be the highest bidder.
