Output range: 65MHz – 800MHz (selectable 1x, 2x, 4x and 8x multipliers).
Low Injection Power for crystal 50uW.
Available outputs: PECL, LVDS, or CMOS.
Integrated variable capacitors.
Supports 3.
3V-Power Supply.
Available in 16 pin (TSSOP or SOIC) VDD XIN XOUT SEL3^ SEL2^ OE VCON GND 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 SEL0^ SEL1^ GND CLKC VDD CLKT GND GND PLL 520-1x DESCRIPTION The PLL520-17/-18/-19 family of VCXO IC’s is specifically designed to pull high frequency fundamental crystals.
They achieve very low current into the crystal resulting in better overall stability.
Their internal varicaps allow an on chip frequency pulling, controlled by the VCON input.
