GS1540, GS1545.
DESCRIPTION
The GO1515 is a self contained, miniature Voltage
Controlled Oscillator (VCO) that is used in conjunction with
Gennum's HD-LINXTM ICs. It produces a clean 1.485GHz
reference clock signal for such devices as the GS1515
HDTV Reclocker and other HD-LINXTM 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 50
strip lines.
The GO1515 VCO is used with the following HD-LINXTM 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
0C to +70C.

SOLDERING RECOMMENDATIONS
Reflow 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
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.
Fig. 3 PCB Warp
Soldering Conditions
Recommended soldering conditions are as follows:
Reflow Soldering
Preheating
15010C, 60 to 120 sec.
Soldering
Peak 2305C
Over 200C 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.
Solder Type
Use solder H60, H63 (in JIS Z 3282) or an equivalent type.
This also applies to solder paste.

HANDLING RECOMMENDATIONS
Cleaning
Do not wash the devices.
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 (Cl
