DATA SHEET

GENERAL DESCRIPTION

FEATURES

The 843001 is a Fibre Channel Clock Generator and a member

of the family of high performance devices from IDT. The 843001

uses either a 26.5625MHz or a 23.4375 crystal to synthesize

106.25MHz, 187.5MHz or 212.5MHz, using the FREQ_SEL pin.

The 843001 has excellent <1ps phase jitter performance, over the

637kHz – 10MHz integration range. The 843001 is packaged in a

small 8-pin TSSOP, making it ideal for use in systems with limited

board space.

• One differential 3.3V LVPECL output

• Crystal oscillator interface designed for 23.4375MHz or

26.5625MHz, 18pF parallel resonant crystal

• Selectable 106.25MHz, 187.5MHz or 212.5MHz

output frequency

• VCO range: 560MHz - 680MHz

• RMS phase jitter @ 106.255MHz, using a 26.5625MHz crystal

(637kHz - 10MHz): 0.74ps (typical)

• RMS phase noise at 106.25MHz

Phase noise:

100Hz ................-95.2 dBc/Hz

1KHz ..............-118.7 dBc/Hz

10KHz ..............-129.1 dBc/Hz

100KHz ..............-129.6 dBc/Hz

• 3.3V operating supply

• -30°C to 85°C ambient operating temperature

• Available in lead-free (RoHS 6) package
