HD-LINX ™ GO1515 Voltage Controlled Oscillator DATA SHEET DESCRIPTION • generates 1.485GHz or 1.485/1.001GHz signal for HD-LINX™ ICs The GO1515 is a self contained, miniature Voltage Controlled Oscillator (VCO) that is used in conjunction with Gennum’s HD-LINX™ ICs. It produces a clean 1.485GHz reference clock signal for such devices as the GS1515 HDTV Reclocker and other HD-LINX™ devices. The control voltage range is from 3.10 volts to 4.65 volts and is derived from the on-chip PLLs. The GO1515 frequency can be pulled approximately 16MHz for every one volt of control. • low current consumption • 50Ω output impedance • operates from a single 5V supply • 8 pin tape on reel APPLICATIONS The output level is approximately 1.0dBm with low spurious and noise content. It is designed to drive 50Ω strip lines. VCO for the following HD-LINX™ ICs: GS1515, GS1522, GS1540, GS1545. The GO1515 VCO is used with the following HD-LINX™ ICs; GS1515, GS1522, GS1540, GS1545 and is ordered as a separate item. The VCO requires a single 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.

Do not reflow the device more than twice. Recommended soldering conditions are as follows: Reflow Soldering 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 2, the device will not be cracked or damaged. Preheating 150±10°C, 60 to 120 sec. Soldering Peak 230±5°C Over 200°C within 30 sec. Soldering Flux Do not use cleaning type flux. Washing the devices after using cleaning type flux may damage inner parts and affect performance. VCO Solder Type PCB MAX 2mm Use solder H60, H63 (in JIS Z 3282) or an equivalent type. This also applies to solder paste. Fig. 3 PCB Warp 3 522 - 40 - 02 230 ± 5 GO1515 TEMPERATURE (˚C) 200 160 30 sec 140 60 to 120 sec 60 sec TIME (sec.) Fig. 3 Reflow Profile HANDLING RECOMMENDATIONS Cleaning Do not wash the devices. Storage Use within 6 months after delivery. If the devices are stored for more than one year, solderability may be degraded. 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.). CAUTION ELECTROSTATIC SENSITIVE DEVICES DO NOT OPEN PACKAGES OR HANDLE EXCEPT AT A STATIC-FREE WORKSTATION REVISION NOTES: Added Soldering and Handling sections and figures.
