General Description
Functional Diagram
The HMC628LP4(E) is a digitally controlled variable
gain amplifier which operates from 50 to 800 MHz,
and can be programmed to provide anywhere from
8 dB attenuation, to 15 dB of gain, in 1.0 dB steps.
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.

HMC628LP4 / 628LP4E
v05.0209
BiCMOS MMIC 5-Bit DIGITAL
VARIABLE GAIN AMPLIFIER, 50 - 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.

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.

Power-Up States
PUP Truth Table
The Power-up (PUP) states work in both serial and
parallel modes, provided that LE is held low. The
DVGA latches in the state of the B4-B0 pins 200 ms
after power-up. The state of B4-B0 pins should be
held firmly high or low for at least 250 ms following
power-up. The PUP state is locked out after the first
LE pulse, until Vdd drops below 4.5V.

List of Materials for Evaluation PCB See Table[1]
The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Hittite upon request.
