OCXO 10MHz 20m 30m 80m frequency reference OCS101Constant temperature crystal module description This module outputs the frequency accuracy of the 10MHz signal (+/-200ppb), has two signal outputs, and one is a standard 10MHz signal.The other is a 10MHz multiplier signal. The multiplier signal has 9 selection frequencies, which are 2X, 3X, 3.125X, 4X, 5X, 5.3125X, 6X, 6.25X, 8X.The different multipliers are selected by the JP1 jumper pin. Correct the deviation of the 10Mhz output frequency (+/-2.0ppm) with the RV1 potentiometer.1. P1: Power input interface; (7~9V).2. P2: 10MHz signal output interface; (10Mhz amplitude: 3Vpp) SMA interface3. P3: N frequency output interface of 10MHz signal; (N*10Mhz amplitude: 5Vpp) SMA interface4. RV1: Correct the deviation of the 10Mhz output frequency (+/-2.0ppm) 5.JP1 jumper needle selectionS1=0,S0=0, OUT = 4XS1=0,S0=M, OUT = 5.3125XS1=0,S0=1, OUT = 5XS1=M,S0=0, OUT = 6.25XS1=M,S0=M, OUT = 2XS1=M,S0=1, OUT = 3.125XS1=1,S0=0, OUT = 6XS1=1,S0=M, OUT = 3XS1=1,S0=1, OUT = 8X0 = connect directly to ground(L)1 = connect directly to VDD(H)M = leave unconnected(floating)
