SYA75603A/03B/604A/04B
2/4 Outputs Ultra-Low Additive Jitter PCIe 1/2/3/4/5/6 Clock Buffer
for Automotive
General Description
Features
The SYA75603A, SYA75603B, SYA75604A, and
SYA75604B are industry leading PCIe clock buffers
with ultra-low additive jitter:
• Two (SYA75603A/03B) and Four
(SYA75604A/04B) PCIe 1/2/3/4/5/6 Compliant
Outputs
• Ultra-Low Additive Jitter 10 fs (PCIe Gen5) and
6 fs (PCIe Gen6)
- 6 fs (PCIe 6.0)
- 10 fs (PCIe 5.0)
• Supports Frequencies of up to 250 MHz
• Transparent for Spread Spectrum
- 20 fs (PCIe 3.0/4.0)
- 52 fs in the 12 kHz to 20 MHz band
• Supports 1.8V ±10%, 2.5V ±10% and 3.3V ±10%
Power Supplies
They can be used in all PCIe 1/2/3/4/5/6 common clock
and SRIS applications.
• Outputs Low Power HCSL with Embedded 85Ω
(SYA75603A/04A) and 100Ω (SYA75603B/04B)
Termination Resistors
SYA75603A/03B and SYA75604A/04B are two and
four output (respectively) PCIe clock buffers with glitch
free per-output enable/disable control hardware pins.
Both devices are packaged in a 3 mm x 3 mm VQFN.
• Individual Glitch Free Output Enable (OExb)
Control Pins
The SYA75603A/03B/604A/04B 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.
• Accepts DC Coupled HCSL Input Signal and AC
Coupled PECL, LVDS and CML
• Extended Temperature Range: –40°C to +105°C
• 3 mm x 3 mm VQFN Package
Applications
