64-Pin (9mm × 9mm) QFN Package

The digital output can be either differential LVDS or

single-ended CMOS. There are two format options for the

CMOS outputs: a single bus running at the full data rate or

demultiplexed buses running at half data rate. A separate

output power supply allows the CMOS output swing to

range from 0.5V to 3.6V.

APPLICATIONS

■

Telecommunications

–

The ENC and ENC inputs may be driven differentially

or single-ended with a sine wave, PECL, LVDS, TTL or

CMOS inputs. An optional clock duty cycle stabilizer al-

lows high performance at full speed with a wide range of

clock duty cycles.
