Description
(Top View)
The Si534 quad frequency XO utilizes Silicon Laboratories’ advanced
DSPLL circuitry to provide a low jitter clock at high frequencies. The Si534
FS[1]
7
®
is available with any-rate output frequency from 10 to 945 MHz and select
frequencies to 1400 MHz. Unlike a traditional XO where a different crystal is
required for each output frequency, the Si534 uses one fixed crystal 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 Si534 IC-based XO is factory
configurable for a wide variety of user specifications including frequency,
supply voltage, output format, and temperature stability. Specific
configurations are factory programmed at time of shipment, thereby
eliminating long lead times associated with custom oscillators.

The Si534 XO was designed to support a variety of options including frequency, temperature stability, output
format, and V . Specific device configurations are programmed into the Si534 at time of shipment. Configurations
DD
can be specified using the Part Number Configuration chart below. Silicon Laboratories 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 Si534 is supplied in an industry-standard, RoHS

1st Option Code
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 quad 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 quad XOs programmed with
the highest frequency value selected when FS[1:0] = 00, and the lowest value when
FS[1:0] = 11.

Example Part Number: 534AB000108BGR is a 5 x 7 mm quad XO in a 8 pad package. Since the six digit code (000108) is >
000100, f0 is 644.53125 MHz (lower frequency) and f1 is 693.48299 (higher frequency), with a 3.3 V supply and LVPECL output.
Temperature stability is specified as ± 20 ppm. The part is specified for a –40 to +85 C° ambient temperature range operation and is
shipped in tape and reel format.
