General Description
The HMC627LP5(E) is a digitally controlled variable
gain amplifier which operates from 50 MHz to 1 GHz,
and can be programmed to provide anywhere from
11.5 dB attenuation, to 20 dB of gain, in 0.5 dB steps.
The HMC627LP5(E) delivers noise figure of 4.3 dB
in its maximum gain state, with output IP3 of up to
+36 dBm in any state. The dual mode gain control
interface accepts either three wire serial input or 6
bit parallel word. The HMC627LP5(E) also features a
user selectable power up state and a serial output for
cascading other Hittite serially controlled components.
The HMC627LP5(E) is housed in a RoHS compliant
5x5 mm QFN leadless package, and requires no
external matching components.

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.

Parallel Mode (Direct Parallel Mode & Latched Parallel Mode)
Note: The parallel mode is enabled when P/S is set to low.
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.

PUP Truth Table
Power-Up States
If LE is set to logic LOW at power-up, the logic state of
PUP1 and PUP2 determines the power-up state of the
part per PUP truth table. If the LE is set to logic HIGH
at power-up, the logic state of D0-D5 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.
