Specifications of IDTM665-02AAAD

Lead Free Status / RoHS Status
Supplier Unconfirmed
G
The M665 is a dual SAW, selectable frequency VCSO
noise and very low jitter. The M665-01 is available in
a range of center frequencies from 125 to 175 MHz.
The M665-02 provides 500 to 700 MHz. Guaranteed
minimum pull-range of ±120 ppm meets GbE
requirements. (It also fully satisfies ±50 ppm minimum
pull-range specification commonly required.) Industry-
standard Kvco (VCO Gain) provides full replacement
compatibility. The M665 is well suited for phase-locked
loop implementations, clock and data recovery circuits,
and other timing applications in telecom and optical
fiber networking systems (e.g., OC-48).
F
◆ Two integrated SAW devices and selectable output
◆ M665-01 output frequencies from 125 to 175 MHz
◆ Industry-standard Kvco for full compatibility
◆ Low phase jitter 0.2ps rms typical for the M665-02
◆ Differential 3.3V LVPECL output
◆ Single 3.3V power supply
◆ Small 9 x 14mm SMT (surface mount) package
