Maxim's frequency synthesizers with sub-picosecond jitter for high-speed systems

Maxim has introduced the MAX3671/MAX3673, a low-jitter frequency synthesizer accepts two reference clock inputs and generates nine phase-aligned LVPECL outputs targeting high-speed systems.

The key features of MAX3671 are,

MAX3671: Input frequencies: 62.5MHz, 125MHz, 250MHz, and 312.5MHz
Output frequencies: 62.5MHz, 125MHz, 156.25MHz, 250MHz, 312.5MHz
MAX3673: Input frequencies: 61.44MHz, 122.88MHz, 245.76MHz, and 307.2MHz
Output frequencies: 61.44MHz, 122.88MHz, 153.6MHz, 245.76MHz,
307.2MHz
Low-Jitter generation: 0.3psRMS (12kHz to 20MHz)
Clock failure indicator for both reference clocks
External feedback provides zero-delay capability
Low output skew: 20ps Typical

The MAX3671 is ideal for jitter cleanup, frequency translation, and clock distribution in Gigabit Ethernet applications where as the MAX3673 is ideal for jitter cleanup, frequency translation, and clock distribution in wireless base-station applications.

Operating temperature range: -45°C to +85°C
Operating input voltage: 3.3V ±5%
Package: Lead-free, 56-pin TQFN package
Price: Starts at $10.26 for 1k pieces
Avilability: Evaluation kits are available to speed designs.
