The HMC628LP4(E) delivers noise figure of 5 dB in its maximum gain state, with output IP3 of up to +35 dBm in any state. The dual mode control interface is CMOS/ TTL compatible, and accepts either a three wire serial input or a 5 bit parallel word. The HMC628LP4(E) also features a user selectable power up state and a serial output port for cascading other Hittite serial controlled components. The HMC628LP4(E) is housed in a RoHS compliant 4x4 mm QFN leadless package, and is available in three evaluation board configurations, depending on the application frequency. 12 VARIABLE GAIN AMPLIFIERS - DIGITAL - SMT Electrical Specifi cations, TA = +25° C, 50 Ohm System, Vdd= +5V 50 - 250 Parameter Min.

800 MHz Serial Control Interface The HMC628LP4(E) contains a 3-wire SPI compatible digital interface (DATA, CLK, LE). It is activated when P/S is kept high. The 5-bit serial word must be loaded MSB first. The positive-edge sensitive CLK and LE requires clean transitions. Standard logic families work well. If mechanical switches were used, sufficient debouncing should be provided. When LE is high, 5-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 (DATA, CLK, LE) are disabled and serial input register is loaded asynchronously with parallel digital inputs (B0-B4). When Le is high, 5-bit parallel data is transferred to the attenuator. For all modes of operations, attenuation state will stay constant while LE is kept low. 12 VARIABLE GAIN AMPLIFIERS - DIGITAL - SMT 12 - 41 Parameter Min. serial period, tSCK Control set-up time, tCS Control hold-time, tCH LE Set up-time, tLN Min.

Direct Parallel Mode - The attenuation state is changed by the Control Voltage Inputs directly. The LE (Latch Enable) must be at a logic high to control the attenuator in this manner. Latched Parallel Mode - The attenuation state is selected using the Control Voltage Inputs and set while the LE is in 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.

If the LE is set to logic HIGH at power-up, the logic state of B4-B0 determines the power-up state of the part per truth table. The DVGA latches in the desired power-up state approximately 200 ms after power-up.
