8P34S1204

Datasheet

Description

Features

The 8P34S1204 is a high-performance differential LVDS fanout

buffer. The device is designed for the fanout of 1PPS signals or

high-frequency, very low additive phase-noise clock and data

signals. The 8P34S1204 supports fail-safe operation and is

characterized to operate from a 1.8V or 2.5V power supply.

• Four low skew, low additive jitter LVDS output pairs

• Two selectable, differential clock input pairs

• Differential CLK, nCLK pairs can accept the following

differential input levels: LVDS, CML

• Maximum input clock frequency: 1.5GHz

• LVCMOS/LVTTL interface levels for the control input select

• Output skew: 10ps (typical)

Guaranteed low output-to-output and part-to-part skew

characteristics make the 8P34S1204 ideal for those clock

distribution applications demanding well-defined performance and

repeatability. Two selectable differential inputs and four low skew

outputs are available. The integrated bias voltage reference

enables easy interfacing of single-ended signals to the device

inputs. The device is optimized for low power consumption and

low additive phase noise.

• Propagation delay: 400ps (maximum)

• Low propagation delay variation across temperature for 1PPS

applications

• Low additive phase jitter, RMS; f_REF= 156.25MHz,

10kHz–20MHz: 34fs (typical)

• Device current consumption (I_DD):

• 65mA typical: 1.8V

• 75mA typical: 2.5V

• Full 1.8V or 2.5V supply voltage

• Lead-free (RoHS 6), 16-Lead VFQFPN package

• -40°C to +85°C ambient operating temperature

• Supports case temperature up to +105°C

• Supports PCI Express Gen 1-5
