SY75602A/02B/603A/03B/604A/04B
2/4 Outputs Ultra-Low Additive Jitter PCIe 1/2/3/4/5/6 Clock Buffer
Features
General Description
• Two (SY75602A/02B/603A/03B) and Four
(SY75604A/04B) PCIe 1.0, 2.0, 3.0, 4.0, 5.0, and
6.0 Compliant Outputs.
The SY75602A/02B/03A/03B/04A/04B are industry
leading PCIe clock buffers with ultra-low additive jitter:
- 6 fs (PCIe 6.0)
• Ultra-Low Additive Jitter 10 fs (PCIe Gen5) and
6 fs (PCIe Gen6)
- 10 fs (PCIe 5.0)
- 20 fs (PCIe 3.0/4.0)
- 52 fs in 12 kHz to 20 MHz band
• Supports Frequencies of up to 250 MHz
• Transparent for Spread Spectrum
They can be used in all PCIe 1/2/3/4/5/6 common clock
and SRIS applications.
• Supports 1.8V ±10%, 2.5V ±10%, and 3.3V ±10%
Power Supplies
SY75602A/02B
(1.4 mm x 1.6 mm VDFN) two output PCIe clock
buffers.
are
the
industry’s
smallest
• Outputs Low Power HCSL with Embedded 85Ω
(SY75602A/03A/04A) and 100Ω
(SY75602B/03B/04B) Termination Resistors
SY75603A/03B and SY75604A/04B are two and four
output PCIe clock buffers with glitch free per-output
enable/disable control hardware pins. Both devices are
packaged in 3 mm x 3 mm VQFN.
• Individual Glitch Free Output Enable (OExb)
Control Pins on SY75603/604
• Accepts DC-Coupled HCSL Input Signal and
AC-Coupled PECL, LVDS, and CML
The devices have embedded low-dropout regulators
(LDO) for superior power noise supply rejection. They
support 1.8V, 2.5V, and 3.3V supplies with tolerance of
±10% which exceeds ±9% required by PCIe Card
Electro Mechanical Specification.
• Extended Temperature Range: –40°C to +105°C
• 1.4 mm x 1.6 mm VDFN (SY75602A/02B) and
3 mm x 3 mm VQFN (SY75603A/03B/604A/04B)
Package
Applications
All six parts have extended temperature range:
–40°C to +105°C.
• PCIe Graphics Cards
• PCIe Based SSD drives
• Laptops and Desktop Computers
• Servers
