PX7 Single Frequency HPLL XO PX7 Features Features Description Applications The PX7 is a crystal oscillator, XO, based upon ectron s HPLL high performance phase locked loop frequency multiplier ASIC, that combines key digital synthesis techniques with I s proven core analog technology blocks. A standard low frequency crystal provides the reference to the fractionaln synthesizer so that virtually any frequency between 0MHz and 00 MHz can be factory programmed allowing quick turn manufacturing.

Parameters are tested with production test circuit (See Figure for LCMOS, Figure 3 for LPECL and Figure 4 for LDS). Parameters are tested at ambient temperature with test limits guardbanded for specified operating temperature. Measured as the maximum deviation from the best straightline fit, per MIL030. Parameters are described with waveform diagram below (Figure ). Not tested in production, guaranteed by design, verified at qualification.

PX7 Single Frequency HPLL XO LPECL Application Diagrams nf nf 30 30 40 40 8 8 Figure Single Resistor Termination Scheme Resistor values are typically 0 to 40 ohms for 3.3 operation and 8 to 0 ohms for. operation. Figure 7 Pull Up Pull Down Termination Resistor values are typically for 3.3 operation For. operation, the resistor to ground is ohms and the resistor to supply is 40 ohms There are numerous application notes on terminating and interfacing PECL logic and the two most common methods are a single resistor to ground, Figure, and a pullup/pulldown scheme as shown in Figure 7. An AC coupling capacitor is optional, depending on the application and the input logic requirements of the next stage. One of the most important considerations is terminating the Output and Complementary Outputs equally. An unused output should not be left unterminated, and if one of the two outputs is left open it will result in excessive jitter on both. PC board layout must take this and 0 ohm impedance matching into account. Load matching and power supply noise are the main contributors to jitter related problems.

PX7 Single Frequency HPLL XO Reliability I qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow simulation. The PX7 family is capable of meeting the following qualification tests: Parameter Environmental Compliance Conditions Mechanical Shock MILSTD883, Method 00 Mechanical ibration MILSTD883, Method 007 Solderability MILSTD883, Method 003 Gross and Fine Leak MILSTD883, Method 04 Resistance to Solvents MILSTD883, Method 0 Moisture Sensitivity Level Handling Precautions IPC/JEDEC JSTD00, MSL Although ESD protection circuitry has been designed into the PX7 proper precautions should be taken when handling and mounting. I employs a human body model (HBM) and a chargeddevice model (CDM) for ESD susceptibility testing and design protection evaluation. ESD Ratings Model Minimum Conditions Human Body Model 000 MILSTD883, Method 30 Charged Device Model 900 JEDEC, JESDC0 Machine Model 00 JEDEC, JESDAA Reflow Profile (IPC/JEDEC JSTD00) Parameter Symbol alue PreHeat Time t S 0 sec Min, 80 sec Max Ramp Up R UP 3 C/sec Max Time Above 7 C t L 0 sec Min, 0 sec Max Time To Peak Temperature T AMBP 480 sec Max Time at 0 C t P 0 sec Min, 40 sec Max Ramp Down R DN C/sec Max The device has been qualified to meet the JEDEC standard for PbFree assembly. The temperatures and time intervals listed are based on the PbFree small body requirements. The temperatures refer to the topside of the package, measured on the package body surface. The PX7 device is hermetically sealed so an aqueous wash is not an issue.
