Si 5 54 Q U A D F R E Q U E N C Y VCXO (10 MH Z T O 1.4 GH Z ) Features Available with any-rate output frequencies from 10-945 MHz and select frequencies to 1.4 GHz Four selectable output frequencies 3rd generation DSPLL(R) with superior jitter performance 3x better frequency stability than SAW-based oscillators Internal fixed crystal frequency ensures high reliability and low aging Available CMOS, LVPECL, LVDS & CML outputs 3.3, 2.5, and 1.8 V supply options Industry-standard 5 x 7 mm package and pinout Pb-free/RoHS-compliant Applications Si5602 Ordering Information: SONET/SDH xDSL 10 GbE LAN / WAN Low jitter clock generation Optical Modules Clock and data recovery Description The Si554 quad frequency VCXO utilizes Silicon Laboratories advanced DSPLL(R) circuitry to provide a very low jitter clock for all output frequencies. The Si554 is available with any-rate output frequency from 10 to 945 MHz and select frequencies to 1400 MHz. Unlike traditional VCXOs where a different crystal is required for each output frequency, the Si554 uses one fixed crystal frequency to provide a wide range of output frequencies. This IC based approach allows the crystal resonator to provide exceptional frequency stability and reliability. In addition, DSPLL clock synthesis provides superior supply noise rejection, simplifying the task of generating low jitter clocks in noisy environments typically found in communication systems. The Si554 IC-based VCXO is factory configurable for a wide variety of user specifications including frequency, supply voltage, output format, tuning slope, and temperature stability. Specific configurations are factory programmed at time of shipment, thereby eliminating long lead times associated with custom oscillators. See page 7. Pin Assignments: See page 6.

Ordering Information The Si554 was designed to support a variety of options including frequency, temperature stability, tuning slope, output format, and VDD. Specific device configurations are programmed into the Si554 at time of shipment. Configurations are specified using the Part Number Configuration chart shown below. Silicon Labs provides a web browser-based part number configuration utility to simplify this process. Refer to www.silabs.com/VCXOPartNumber to access this tool and for further ordering instructions. The Si554 VCXO series is supplied in an industry-standard, RoHS compliant, lead-free, 8-pad, 5 x 7 mm package. Tape and reel packaging is an ordering option. 554 X X XXXXXX B G R R = Tape & Reel Blank = Trays 554 Quad VCXO Product Family Operating Temp Range (C) G -40 to +85 C Device Revision Letter 6-digit Frequency Designator Code Four unique frequencies can be specified within the following bands of frequencies: 10 to 945 MHz, 970 to 1134 MHz, and 1213 to 1417 MHz. A six digit code will be assigned for the specified combination of frequencies. Codes > 000100 refer to XOs programmed with the lowest frequency value selected when FS[1:0] = 00, and the highest value when FS[1:0] = 11. Six digit codes < 000100 refer to XOs programmed with the highest frequency value selected when FS[1:0] = 00, and the lowest value when FS[1:0] = 11. 1st Option Code A B C D E F G H J K M N P Q R S T U V W VDD 3.3 3.3 3.3 3.3 2.5 2.5 2.5 2.5 1.8 1.8 3.3 3.3 3.3 3.3 2.5 2.5 2.5 2.5 1.8 1.8 Output Format Output Enable Polarity LVPECL High LVDS High CMOS High CML High LVPECL High LVDS High CMOS High CML High CMOS High CML High LVPECL Low LVDS Low CMOS Low CML Low LVPECL Low LVDS Low CMOS Low CML Low CMOS Low CML Low Note: CMOS available to 160 MHz. 2nd Option Code Code A B C D E F Temperature Stability ppm (max) 100 100 50 50 20 50 Tuning Slope Kv ppm/V (typ) 180 90 180 90 45 135 Minimum APR (ppm) @ 3.3 V @ 2.5 V @ 1.8 V 100 75 25 30 Note 6 Note 6 150 125 75 80 30 25 25 Note 6 Note 6 100 75 50 Notes: 1. For best jitter and phase noise performance, always choose the smallest Kv that meets the application's minimum APR requirements. Unlike SAW-based solutions which require higher higher Kv values to account for their higher temperature dependence, the Si55x series provides lower Kv options to minimize noise coupling and jitter in realworld PLL designs. See AN255 and AN266 for more information. 2. APR is the ability of a VCXO to track a signal over the product lifetime. A VCXO with an APR of 25 ppm is able to lock to a clock with a 25 ppm stability, over 15 years. 3. Nominal Pull range () = 0.5 x VDD x tuning slope. 4. Nominal Absolute Pull Range (APR) = Pull range - stability - lifetime aging = 0.5 x VDD x tuning slope - stability - 10 ppm 5. Minimum APR values noted above include worst case values for all parameters. 6. Combination not available. Example Part Number: 554AF000124BGR is a 5 x 7 mm Quad VCXO in an 8 pad package. Since the six digit code (000124) is > 000100, f0 is 622.08 MHz (lowest frequency), f1 is 644.53125, f2 is 657.42188, and f3 is 669.32658 MHz (highest frequency), with a 3.3 V supply, LVPECL output, and Output Enable active high polarity. Temperature stability is specified as 50 ppm and the tuning slope is 135 ppm/V. The part is specified for a -40 to +85 C ambient temperature range operation and is shipped in tape and reel format.
