General Description

The 8101925 is a high performance, low jitter/low phase noise

VCXO from IDT. The 8101925 works in conjunction with a 25MHz

pullable crystal to generate an LVCMOS/LVTTL output clock of

25MHz from an input clock of 5MHz or 19.44MHz. The output range

is ±100ppm around the nominal crystal frequency. The device is

packaged in a small 16 TSSOP package and is ideal for use on

space constrained boards.

Features

• One single-ended LVCMOS or LVTTL output

• One single-ended clock accepts the following input types:

LVCMOS, LVTTL

• Output frequency: 25MHz

• Accepts 5MHz or 19.44MHz with auto input frequency detect

• Absolute pull range (APR): ±100ppm

• RMS phase jitter. (12kHz – 5MHz): 0.4ps (typical)

• Full 3.3V supply, or 3.3V core/2.5V output supply

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

• Available in lead-free (RoHS 6) package

• For functional replacement part use 810252
