General Description
LE
The HMC1019LP4E is a broadband 5-bit GaAs IC
digital attenuator in a low cost leadless surface
mount package. Covering 0.1 to 30.0 GHz, the insertion loss is less than 4.0 dB typical. The attenuator
bit values are 0.5 (LSB), 1, 2, 4, 8 for a total attenuation of 15.5 dB. Attenuation accuracy is excellent
at ±0.3 dB typical step error with an IIP3 of +45 dBm.
The control interface is CMOS/TTL compatible and
accepts a three wire serial input. The HMC1019LP4E
features a user selectable power up state and a serialoutput port for cascading other Hittite serial controlled
components.

HMC1019LP4E
v00.0911
0.5 dB LSB GaAs MMIC 5-BIT DIGITAL
ATTENUATOR, 0.1 - 30 GHz
The HMC1019LP4E contains a 3-wire SPI compatible digital interface (SERIN, CLK, LE). The serial control interface
is activated when S/A is kept high. The 5-bit serial word must be loaded MSB first as a 6-bit word with the first
bit ignored. The positive-edge sensitive CLK and LE requires clean transitions. If mechanical switches are 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.

TE
For all modes of operations, the state will stay constant while LE is kept low.

Asynchronous Mode
The HMC1019LP4E can be switched to an asynchronous mode to change the attenuation state rapidly to one of four
predefined states. The logic state of ASM1-ASM2 determines one of the four attenuation states in the asynchronous
mode per truth table. The asynchronous mode works either directly or latched. To activate the direct-asynchronousmode, S/A needs to be at logic low and LE needs to be at logic high. In the direct-asynchronous-mode, any change in
the logic state of ASM1-ASM2 directly affects the attenuation state. In the latched-asynchronous-mode, the attenuation
state changes per the asynchronous mode truth table when S/A is at logic low and LE is pulsed per the timing diagram.
The attenuation stays constant (latched) as long as LE stays low. In the asynchronous mode, the inputs SERIN and
CLK do not affect the attenuation state.
