It is designed to drive 50Ω strip lines. VCO for the GS1560, GS1559 and GS9060 Deserializers, and the GS1532, GS1531 and GS9062 Serializers This component and all homogeneous subcomponents are RoHS compliant. Description GO1555 for new designs 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 The GO1555 should be used for new designs given that it is smaller, consumes less power and gives better jitter performance. VCTR VCC STRIPLINE STRIPLINE OUT OSCILLATOR CIRCUIT GND GO1525 Functional Block Diagram 21969 - 9 February 2007 1 of 9 www.gennum.com FOR NEW DESIGNS USE GO1555 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. Applications • 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.

Soldering Recommendations The device is manufactured with Matte-Sn terminations and is compatible with both standard eutectic and Pb-free solder reflow profiles. The recommended standard eutectic reflow profile is shown in Figure 3-1. The maximum recommended Pb-free reflow profile is shown in Figure 3-2. 60-150 sec. Temperature 10-20 sec. 230˚C 220˚C 6˚C/sec max 150˚C 100˚C 25˚C Time 120 sec. max 6 min. max Figure 3-1: Standard Eutectic Solder Reflow Profile Temperature 60-150 sec. 20-40 sec. 260˚C 250˚C 3˚C/sec max 217˚C 6˚C/sec max 200˚C 150˚C 25˚C Time 60-180 sec. max 8 min. max Figure 3-2: Maximum Pb-free Solder Reflow Profile 21969 - 9 February 2007 5 of 9 FOR NEW DESIGNS USE GO1555 3˚C/sec max 183˚C GO1525 Data Sheet 3.1 Reflow Conditions The device will meet the data sheet specifications after completing the reflow process according to the profile shown in Figure 3-1 or Figure 3-2. Recommended soldering conditions are as follows: Preheating 150±10°C, 60 to 120 sec. Soldering Peak 260°C Over 200°C within 30 sec. Do not use cleaning type flux. Washing the devices after using cleaning type flux may damage inner parts and affect performance. 3.3 Rework or Repair 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. Do not vibrate the VCO during reflow soldering. 3.4 Endurance To Warp 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 3-2, the device will not be cracked or damaged.

Handling Recommendations 4.1 Cleaning There are two options for cleaning the devices. Option 1: 1. Clean but do not use solvent cleaners. 2. Thoroughly dry assemblies afterwards. Option 2: 4.2 Storage 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. Avoid dust, sea breezes and corrosive gases (Cl2, NH3, SO2, NOX, etc.). Use within 6 months after delivery. If the devices are stored for more than one year, solderability may be degraded. 4.3 Transport Package the devices for transportation to avoid mechanical vibration or shock. 4.4 ESD Warning Avoid poor ground connections and electrostatic discharge or induction in production. 21969 - 9 February 2007 7 of 9 FOR NEW DESIGNS USE GO1555 1.
