LPRO101 LPRO-101 Rubidium Clock Interface Board

Description: Item Description: For sale today is one LPRO-101 rubidium clock/oscillator interface board. This is for the board only, the cables and the LPRO-101 in the picture are not included. Condition: This board is an interface for the LPRO-101 Rubidium oscillator. Unlike other interface boards for the LPRO-101, the board can be directly attached to the LPRO-101 as shown in the picture or it can be connected via a male/female ribbon cable. The board does not interfere with the LPRO-101 heat sink surface, the board edge is about 50 mil above the bottom of the LPRO-101. Power is connected through a MOLEX 4 pin micro-fit connector. The mating connector with pigtails will be included. The 24V return is not connected to board ground, only the LPRO-101 24V return pin. The board ground is connected to the LPRO-101 RF ground and chassis ground. This keeps the interface board at the LPRO-101 internal ground potential. The board has an ADR02ARZ 5V reference and a 5K 25 turn potentiometer for adjusting the frequency of the LPRO-101 via the external C-Field Voltage Adjustment pin. Under most circumstances the potentiometer should be about centered (2.500V). The board has an SMA connector for input of an adjustment voltage to adjust the frequency of the LPRO-101. The voltage source must be able to overdrive the adjustment potentiometer (or the potentiometer can be removed). The board has an SMA connector that is directly connected to the LPRO-101 output (sine wave). There is an on board 51ohm resistor that should be removed if connecting to an external 50 ohm load. The board has an SMA connector providing a 10MHz High Speed CMOS output, with a 47 ohm resistor in series. There is provision for a MOLEX 0.1" KK series connector (not populated) to bring the BITE signal out to an external LED. The current limiting resistors (two 499 ohm) are on board so only the LED is needed. There is provision for a 4 pin DF11 series 2mm connector (not populated). This connector has the Lamp Volts (pin 3), Crystal Volts Monitor (pin 1), and BITE (pin 4) signals. Pin 2 is ground. I have a GPS/PLL board that can control the LPRO through this board in another auction listed here: https://www.ebay.com/itm/156528448228 PayPal Confirmed Address: PayPal address must be confirmed and must be the same as the shipping address. Returns: Returns accepted within 30 days. Feedback: Feedback is important to me, please email or contact me with any concerns, issues or problems before leaving feedback and give me the opportunity to work things out if needed. I always leave positive feedback after receiving feedback from the buyer, that way I know the buyer is happy and the transaction is complete. Shipping: Shipping is to USA only for now.
