ETC GO1525

+'/,1; ™,, GO1525
Voltage Controlled Oscillator
DATA SHEET
DESCRIPTION
• generates 1.485GHz or 1.485/1.001GHz signal for
HD-LINX™II ICs
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 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.
• low current consumption
• 50Ω
Ω output impedance
• operates from a single 2.5V supply
• 8 pin tape on reel
APPLICATIONS
• VCO for the GS1560 and GS9060 Deserializers, and the
GS1532 and GS9062 Serializers
The output level is typically -9.0dBm with low spurious and
noise content. It is designed to drive 50Ω strip lines.
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.

3. SOLDERING RECOMMENDATIONS
VCO
3.1 Reflow Conditions
The device will meet the data sheet specifications after
completing the reflow process according to the profile
shown in Figure 1. Recommended soldering conditions are
as follows:
PCB
MAX 2mm
Fig. 2 PCB Warp
Preheating
150±10°C, 60 to 120 sec.
4. HANDLING RECOMMENDATIONS
Soldering
Peak 230±5°C
Over 200°C within 30 sec.
4.1 Cleaning
Do not wash the devices.
3.2 Soldering Flux
4.2 Storage
Do not use cleaning type flux. Washing the devices after
using cleaning type flux may damage inner parts and affect
performance.
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.
3.3 Solder Type
Use solder H60, H63 (in JIS Z 3282) or an equivalent type.
This also applies to solder paste.
Avoid dust, sea breezes and corrosive gases (Cl2, NH3,
SO2, NOX, etc.).
3.4 Rework or Repair
Use within 6 months after delivery. If the devices are stored
for more than one year, solderability may be degraded.
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.
4.3 Transport
Package the devices for transportation to avoid mechanical
vibration or shock.
Do not vibrate the VCO during reflow soldering.
3.5 Endurance To Warp
4.4 ESD Warning
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.
Avoid poor ground connections and electrostatic discharge
or induction in production.
