+'/,1; ™,, GO1525 Voltage Controlled Oscillator DATA SHEET DESCRIPTION • generates 1.485GHz or 1.485/1.001GHz signal for HD-LINX™II ICs The GO1525 is a self contained, miniature Voltage Controlled Oscillator (VCO). It produces a clean 1.485GHz reference clock signal for the GS1560 and GS9060 deserializers, and for the GS1532 and GS9062 serializers. The control voltage range is from 1.0 volts to 1.5 volts and is derived from the on-chip PLLs. The GO1525 frequency can be pulled approximately 32MHz for every one volt of control. • low current consumption • 50Ω Ω output impedance • operates from a single 2.5V supply • 8 pin tape on reel APPLICATIONS • VCO for the GS1560 and GS9060 Deserializers, and the GS1532 and GS9062 Serializers The output level is typically -9.0dBm with low spurious and noise content. It is designed to drive 50Ω strip lines. The VCO requires a single 2.5V supply and draws a maximum of 15mA of current. It is packaged in a miniature 8-pin proprietary surface mount package and operates over the normal commercial temperature range of 0°C to +70°C.

Fig. 1 Reflow Solder Profile 3. SOLDERING RECOMMENDATIONS VCO 3.1 Reflow Conditions The device will meet the data sheet specifications after completing the reflow process according to the profile shown in Figure 1. Recommended soldering conditions are as follows: PCB MAX 2mm Fig. 2 PCB Warp Preheating 150±10°C, 60 to 120 sec. 4. HANDLING RECOMMENDATIONS Soldering Peak 230±5°C Over 200°C within 30 sec. 4.1 Cleaning Do not wash the devices. 3.2 Soldering Flux 4.2 Storage Do not use cleaning type flux. Washing the devices after using cleaning type flux may damage inner parts and affect performance. Store the devices out of direct sunlight, at a stable temperature and humidity. Avoid extreme temperatures, high humidity and wide temperature fluctuations. Condensation on the devices may result in reduced quality and lowered solderability. 3.3 Solder Type Use solder H60, H63 (in JIS Z 3282) or an equivalent type. This also applies to solder paste. Avoid dust, sea breezes and corrosive gases (Cl2, NH3, SO2, NOX, etc.). 3.4 Rework or Repair Use within 6 months after delivery. If the devices are stored for more than one year, solderability may be degraded. Rework or repair must only be done once. Do not reflow the device more than twice; once for initial soldering and once for remounting after rework. 4.3 Transport Package the devices for transportation to avoid mechanical vibration or shock. Do not vibrate the VCO during reflow soldering. 3.5 Endurance To Warp 4.4 ESD Warning When the device is soldered on a printed circuit board (dimension: 100mm x 100mm; thickness: 1.6mm) and the PCB is warped as shown in Figure 2, the device will not be cracked or damaged. Avoid poor ground connections and electrostatic discharge or induction in production. 3 GENNUM CORPORATION 21969 - 2 5.
