The effect on performance is usually most prevalent at high temperatures, where the electronic circuits slow down due to changes in transistor characteristics. The HMC1060LP3E PTAT Mode is designed to counterbalance the effect of temperature changes on devices supplied by the HMC1060LP3E. When PTAT Mode is enabled, the HMC1060LP3E scales output voltage proportionally with temperature, resulting in higher supply voltage at high temperatures and lower supply voltage at lower temperatures, as shown in Figure 6 and Figure 8. Higher supply voltage has the opposite effect as that of temperature increase. It increases supply current and speeds up electronic circuits, thereby improving performance and offsetting the negative effect of high temperature on device performance. HMC1060LP3E PTAT mode is enabled by grounding HMC1060LP3E’s PTATB pin. It is disabled by leaving the PTATB pin of the HMC1060LP3E floating. The rate at which HMC1060LP3E’s PTAT mode scales supply voltage with temperature is optimized to work with Hittite’s Wideband PLLs with Integrated VCOs, such as the HMC830LP6GE. However, this feature is also beneficial for other products as well. Most electronic circuits slow down at higher temperatures. Higher supply voltage at higher temperatures has the opposite effect of speeding up the circuitry by providing more current and thereby improving performance. Output Voltage Configuration All of the outputs of the HMC1060LP3E can be configured to supply anywhere from 1.8 V to 5.2 V. The output voltage is configured using external resistors. PTAT mode can be enabled/disabled for all output options. Default Configuration Three outputs (VR1, VR2, and VR3) supply 3.3 V by default, and one output (VR4) defaults to 5 V. The Default configuration of the HMC1060LP3E is shown in the Application Schematic section of this document. Supply Voltage Less Than Default Configuration The outputs of the HMC1060LP3E are configured to supply voltages less than the default values, down to 1.8 V minimum, by connecting a resistance (Ry in Figure 13) between pins VRx and RDx (where x = 1,2,3,4). Figure 13 shows an example of configuring VR1 output. Other outputs are configured in exactly the same way (ie. Ry is added between VR2 & RD2, VR3 & RD3 and between VR4 & RD4). 6 PTAT Disabled PTAT Enabled OUTPUT VOLTAGE (V) 5 Output VR4 4 3 Outputs VR1, VR2, & VR3 2 1 10 Figure 13.

When using external resistances to configure the HMC1060LP3E to non-default output voltages it may be beneficial to use the R3 resistance value in order to achieve a desired resistance Rx when configuring VR1, VR2, and/or VR3 outputs to voltages greater than default value (3.3 V) Supply Voltage Greater Than Default Configuration To configure any or all of the VR1, VR2, and VR3 outputs of the HMC1060LP3E to supply 5 V, connect the appropriate HV pin (HV1, HV2, and HV3 corresponding to outputs VR1, VR2, VR3 respectively) of the HMC1060LP3E to ground, as shown in Figure 15. This output configuration is only supported if PTAT Mode is disabled.

Rx = R1R2  VRx  − 1 R2 − R1  VREF   (EQ 2) Configuration Examples 1. To set VR1 = VR2 = VR3 = 5 V in with PTAT Mode disabled, pins HV1, HV2 and HV3 are connected to GND. Note that this configuration is only possible when PTAT Mode is disabled. If similar configuration is required with PTAT Mode enabled, configuration provided in example 3 below must be followed. 2. To set VR1 = VR2 = VR3 = 1.8 V in with PTAT Mode disabled, external resistance Ry = 21 kΩ shown in Figure 13 is required. 3. To set VR1 = 5 V in PTAT Mode, external resistance Rx = 40.3 kΩ shown in Figure 16 is required. Please note that for optimal temperature compensation, the 5 V level on VR1 can be achieved by connecting 5.7 kΩ (40.3 kΩ – R3) from HV1 pin to GND (see Output Configuration Table for more detail). This is due to the fact that the internal resistors of the HMC1060LP3E have a temperature coefficient of +270 ppm/°C. When the default output voltage is modified by using an external resistor with a different temperature coefficient, the temperature behavior of the respective output will differ from this specification, although the difference will likely be insignificant. Application Information The HMC1060LP3E ultra low noise regulator features market leading noise performance. It is capable of supplying all of the power needs of Hittite’s Wideband PLL with Integrated VCOs products, such as the HMC830LP6GE, by itself. This capability along with market leading noise performance make the HMC1060LP3E an ideal choice for supplying Hittite’s broad range of PLL with Integrated VCOs products. Figure 18 shows a noise comparison between the HMC1060LP3E and a standard off-the-shelf low noise DC power supply. It illustrates the superior noise performance of the HMC1060LP3E at most frequencies. [4] Example shows the configuration of only VR1 output of the HMC1060LP3E. Other outputs are configured in exactly the same way. VDD input is limited to 5.6 V maximum and Output Voltage + 300 mV minimum. [5] This curve is accurate only in cases where output voltage greater than default is required. Output voltage is limited to 5.2 V maximum for each output. 13 Information furnished by Analog Devices is believed to be accurate and reliable.

HMC830LP6GE Output Power improvement observed as a result of enabling HMC1060LP3E’s PTAT Mode.[6] In some cases, application circuit performance can be enhanced at high temperatures by increasing the input supply voltage as the temperature increases. The HMC1060LP3E offers a PTAT option that has been designed to improve the performance of Hittite’s PLLs with Integrated VCOs. It is also potentially useful in many other applications, but the user needs to verify the performance in a particular application circuit with this mode. Figure 20 and Figure 21 quantify the benefits of HMC1060LP3E’s PTAT mode. Figure 20 shows that the HMC1060LP3E’s PTAT mode enables the HMC830LP6GE to achieve 0.5 dB better Phase Noise performance across all operating frequencies at +85°C. Similarly, Figure 21 shows that the HMC1060LP3E’s PTAT mode enables the HMC830LP6GE to achieve up to 0.8 dB increase in output power at +85°C across all operating frequencies. External Enable Pin & Power-Up Timing The HMC1060LP3E features an external Enable pin (EN) that can be used to enable/disable the outputs of the HMC1060LP3E. This feature is especially useful in complex systems where the power-up and power-down procedure of various subsystems requires precise management. HMC1060LP3E’s enable pin (EN) allows the controller to powercycle and turn on/off all of the circuits and components supplied by the HMC1060LP3E. 5 5 HMC1060LP3E VR4 Output 4 4 VOLTAGE (V) VOLTAGE (V) HMC1060LP3E VR4 Output 3 HMC1060LP3E ENABLE Pin 2 3 HMC1060LP3E ENABLE Pin 2 HMC1060LP3E VREF Pin HMC1060LP3E VREF Pin 1 1 0 -0.05 0 0.05 0.1 0 -0.05 0.15 TIME (S) Figure 22.

As an example Figure 22 and Figure 23 show that using a 1 µF capacitor on the REF pin of the HMC1060LP3E instead of 4.7 µF can reduce speed of the power up by approximately 15 milliseconds.
