ABV0235/-37/-38/-39 750kHz - 800MHz Low Phase Noise Multiplier VCXO Universal Low Phase Noise IC's FEATURES * * * * * * * * * * Selectable 750kHz to 800MHz range. Low phase noise output (@ 10kHz frequency offset, -142dBc/Hz for 19.44MHz, -125dBc/Hz for 155.52MHz, -115dBc/Hz for 622.08MHz). CMOS (ABV0237), PECL (ABV0235 and ABV0238) or LVDS (ABV0239) output. 12 to 25MHz crystal input. No external load capacitor or varicap required. Output Enable selector. Wide pull range (+/-200 ppm) Selectable 1/16 to 32x frequency multiplier. 3.3V operation. Available in 16-Pin (TSSOP or 3x3mm QFN).

They provide phase noise performance as low as -125dBc at 10kHz offset (at 155MHz), by multiplying the input crystal frequency up to 32x. The wide pull range (+/- 200 ppm) and very low jitter make them ideal for a wide range of applications, including SONET/SDH and FEC. They accept fundamental parallel resonant mode crystals from 12 to 25MHz. ^: *: XOUT SEL3^ SEL2^ OE 12 13 14 15 16 11 9 8 7 6 5 SEL1^ DESCRIPTION XIN VDD / GND* GND CLKC VDD CLKT A023x 1 2 3 4 VCON GND GND BLOCK DIAGRAM SEL OE Vi n X+ XOscillator Amplifier w/ integrated varicaps PLL (Phase Locked Loop) Internal pull-up On 3x3 package, ABV0235/-38 do not have SEL0 available: Pin 10 is VDD, pin 11 is GND.

It is assumed that the crystal will be at nominal frequency at this load. If the crystal requires more load to be at nominal frequency, the additional load must be added externally. This however may reduce the pull range. 3.
