GO1515_05

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 • Pb-free APPLICATIONS VCO for the following HD-LINX™ ICs: GS1515, GS1522, GS1540, GS1545. 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 Flux The device will meet the data sheet specifications after completing the reflow process according to the profile shown in Figure 3 or Figure 4. Do not reflow the device more than twice. Endurance To Warp Do not use cleaning type flux. Washing the devices after using cleaning type flux may damage inner parts and affect performance. 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.

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.).
