FemtoClock Family Addresses Complex Timing Networks

FemtoClock Family Addresses Complex Timing Networks

Said to be a uniquely flexible frequency synthesizer with eight fractional and two integer output dividers, the 8T49N1012 FemtoClock NG synthesizer delivers a single-chip solution that aids design engineers in resolving complex timing requirements. The clock is programmable through an I2C interface and also supports master capability, allowing the register configuration to be read from an external EEPROM. The Timing Commander software tool enables fast and easy reconfiguration of the device. Other features include 12 differential or 2x12 in-phase LVCMOS clocks, two integer output dividers that provide an additional four outputs, phase jitter performance of less than 500 fs rms phase jitter (12 kHz to 20 MHz), output frequencies from 8 kHz up to 1 GHz differential, 250 MHz LVCMOS, and skew control on all fractional output dividers allow for adjustments in steps as small as 16ps. The 8T49N1012 FemtoClock NG synthesizer is available in a 10 x 10 mm 72-VFQFN package. Pricing is $4.60 each/10,000.
