the HmC625Hflp5e is a digitally controlled variable
gain amplifier which operates from 0.5 - 6 GHz, and
can be programmed to provide anywhere from 13.5
db attenuation, to 18 db of gain, in 0.5 db steps. the
HmC625Hflp5e delivers noise figure of 6 db in its
maximum gain state, with output ip3 of up to +33 dbm
in any state. the dual mode control interface is CmOs/
ttl compatible, and accepts either a three wire serial
input or a 6 bit parallel word. the HmC625Hflp5e also
features a user selectable power up state and a serial
output port for cascading other Hittite serial controlled
components. the HmC625Hflp5e is housed in a
roHs compliant 5 x 5 mm Qfn leadless package, and
requires no external matching components.

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.

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.

Variable Gain amplifiers - DiGital - smt
the HmC625Hflp5e 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.

Power-On Sequence
The ideal power-up sequence is: GND, Vdd, digital
inputs, rf inputs. the relative order of the digital
inputs are not important as long as they are powered
after Vdd / GnD
note: the logic state of D0 - D5 determines the power-
up state per truth table shown below when le is high
at power-up.

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.
