SAN JOSE, CALIF. Pericom Semiconductor Corp. is offering a pair of 3.3-volt, zero-delay clock buffers in commercial and industrial temperature ranges for applications including Gigabit Ethernet, Fast Ethernet, ATM/Sonet, SDRAM and PCI buffering in servers and workstations.
The PI6C2305 has a bank of four outputs plus a fifth output, while the PI6C2309 has two banks of four out-puts plus a ninth output. The fifth and ninth outputs are internally connected to the feedback in their respective versions.
Sergis Mushell, silicon clock product marketing engineer, said one or both banks of outputs in the PI6C2309 can be turned off to minimize power consumption and reduce power supply noise.
Both devices have a frequency range from 10 to 100 MHz, less than 200-picosecond input-to-output propagation delay, less than 400-ps device-to-device skew, less than 200-ps cycle-to-cycle jitter and less than 250-ps output-to-output skew.
The PI6C2305 is priced at $3.18 and the PI6C2309 at $3.98 in quantities of 10,000. The PI6C2305 comes in an eight-pin small-outline IC and the PI6C2309 in 16-pin, 150-mil SOIC and TSSOP packages.
