GO1515

HD-LINX ™ GO1515 Voltage Controlled Oscillator DATA SHEET FEATURES • generates 1.485GHz or 1.485/1.001GHz signal for HD-LINX™ ICs • low current consumption • 50Ω output impedance • operates from a single 5V supply • 8 pin tape on reel APPLICATIONS VCO for the following HD-LINX™ ICs: GS1515, GS1522, GS1540, GS1545. ORDERING INFORMATION PART NUMBER GO1515 - CTA PACKAGE 8 pin tape on reel TEMPERATURE 0°C to 70°C DESCRIPTION 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. The output level is approximately 1.0dBm with low spurious and noise content. It is designed to drive 50Ω strip lines. 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.

SOLDERING RECOMMENDATIONS Reflow Conditions Soldering Conditions The device will meet the data sheet specifications after completing the reflow process according to the profile shown in Figure 3. Do not reflow the device more than twice. Endurance To Warp Recommended soldering conditions are as follows: Reflow Soldering Preheating Soldering 150±10°C, 60 to 120 sec. Peak 230±5°C Over 200°C within 30 sec. 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. VCO PCB Soldering Flux Do not use cleaning type flux. Washing the devices after using cleaning type flux may damage inner parts and affect performance. Solder Type MAX 2mm Use solder H60, H63 (in JIS Z 3282) or an equivalent type. This also applies to solder paste.

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. Use within 6 months after delivery. If the devices are stored for more than one year, solderability may be degraded. 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 DOCUMENT IDENTIFICATION DATA SHEET The product is in production. Gennum reserves the right to make changes at any time to improve reliability, function or design, in order to provide the best product possible.
