HMC627LP5 / 627LP5E v10.0410 0.5 dB LSB GaAs MMIC 6-BIT DIGITAL VARIABLE GAIN AMPLIFIER, 50 MHz - 1 GHz Serial Control Interface The HMC627LP5(E) contains a 3-wire SPI compatible digital interface (SERIN, CLK, LE). It is activated when P/S is kept high. The 6-bit serial word must be loaded MSB first. The positive-edge sensitive CLK and LE requires clean transitions. If mechanical switches were used, sufficient debouncing should be provided. When LE is high, 6-bit data in the serial input register is transferred to the attenuator. When LE is high CLK is masked to prevent data transition during output loading. When P/S is low, 3-wire SPI interface inputs (SERIN, CLK, LE) are disabled and serial input register is loaded asynchronously with parallel digital inputs (D0-D5). When Le is high, 6-bit parallel data is transferred to the attenuator. For all modes of operations, the DVGA state will stay constant while LE is kept low. 12 T M S - L A T I G I D - S Parameter Typ.

A Direct Parallel Mode - The attenuation state is changed by the Control Voltage Inputs directly. The LE (Latch Enable) I R must be at a logic high to control the attenuator in this manner. A Latched Parallel Mode - The attenuation state is selected using the Control Voltage Inputs and set while the LE is in V the Low state. The attenuator will not change state while LE is Low. Once all Control Voltage Inputs are at the desired states the LE is pulsed. See timing diagram above for reference.
