TCXO NG772 for ICOM IC7700/IC7800

The new high precision NG772 TCXO replacement for the ICOM IC7700/IC7800 transceivers

This board is a replacement for the ICOM CR772 OCXO unit (ICOM part number 6050012210).

The NG772 is mechanically and electrically 100% compatible with the original ICOM CR772 OCXO unit, with the same dimensions and all soldering pads are in the same location as on the original unit, which permit a easy replacement of a original CR772 unit. Furthermore this new TXCO unit permit the same fine frequency adjustment with the "Ref. Adj." in the service menu of the IC7700/IC7800.
The high quality TCXO from IQD used on this module providing a high degree of frequency stability over a wide temperature range, extremely low spurious levels and a low noise voltage regulator for a very clean supply. So there are no warm-up delays like with the orginal CR772 OCXO unit, because no heater are necessary for a TCXO (Temperature Compensated Crystal Oscillator)
The board is delivered as full assembled and tested, so is it quite easy for most people with soldering skills to replace the original CR772 unit in the transceiver.

The specifications:

- Output frequency: 10MHz
- Frequency stability: +-0,28ppm (or with extra high stability option: 0,1ppm)
- Operating Temperature Range: -20 to 70C
- Frequency tuning range: +100Hz/-100Hz
- Power supply requirements: 4,5 to 28 VDC, max. 10mA (or with extra high stability option: 4,5 to 12 VDC, max. 49mA)

Each TCXO NG772 is shipped as tested in our lab with a Rubidium frequency standard.
