The circuit can be programmed to divide from N = 1 to N = 4 in the 2 MHz to 2 GHz input frequency range. The high level output power (up to 1 dbm) with a very low SSB phase noise and % duty cycle makes this device ideal for low noise clock generation, LO generation and LO drive applications. Configurable bias controls allow power minimization of up to 2%. Electrical Specifications, T A = +2 C, Vcc = +V, Z o = Ω, Bias1 = GND Parameter Conditions Min. Typ. Max.

Divider Positive Output, Open Drain. Typically 1 Ohms connected to Vcc. External Bypass Decoupling for Precision/Low Noise Bias Circuit Application Note: The is a high performance RF divider. Such dividers are high gain devices with internal feedback. The device will oscillate if used with AC coupled RF inputs and if no RF input is applied. Normally, if the RF input signal is removed the device should be disabled, or it should be placed in divide by 1 mode. The device is stable in divide by one mode with no RF input. The device will oscillate in divide 2, 3, or 4 modes with no RF input. In general very small RF input levels will stop all oscillations. At the minimum rated RF input sensitivity level or higher, no oscillations or spurious signals exist and excellent low noise performance is achieved. For input frequency lower than 2 MHz, square wave input signal is recommended. The divider output power for the differential mode, shows a roll off at lower frequencies due to the limited frequency range of the T6 & T7 (4:1) RF transformers, MHz to 3 MHz.
