Si53320-28 Data Sheet
Low-Jitter LVPECL Fanout Clock Buffers with up to 10 LVPECL
Outputs from Any-Format Input and Wide Frequency Range from
DC up to 1250 MHz
The Si53320–28 family of LVPECL fanout buffers is ideal for clock/data distribution
and redundant clocking applications. These devices feature typical ultra-low jitter char-
acteristics of 50 fs and operate over a wide frequency range from dc to 725/1250
MHz. Built-in LDOs deliver high PSRR performance and reduce the need for external
components, simplifying low-jitter clock distribution in noisy environments.
The Si53320–28 family is available in multiple configurations, with some versions offer-
ing a selectable input clock using a 2:1 input mux. Other features include independent
output enable and built-in format translation. These buffers can be paired with the
Si534x clocks and Si5xx oscillators to deliver end-to-end clock tree performance.
KEY FEATURES
• Ultra-low additive jitter: 50 fs rms
• Built-in LDOs for high PSRR performance
• Up to 10 LVPECL Outputs
• Any-format Inputs (LVPECL, Low-power
LVPECL, LVDS, CML, HCSL, LVCMOS)
• Wide frequency range: dc to 1250 MHz
• Output Enable option
• Multiple configuration options
• Dual Bank option
• 2:1 Input Mux operation
• RoHS compliant, Pb-free
• Temperature range: –40 to +85 °C

 Si53326
Si53320-28 Data Sheet • Functional Description
2. Functional Description
The Si53320-28 are a family of low-jitter, low-skew, fixed-format (LVPECL) buffers. All devices except the Si53326 and Si53328 have
a universal input that accepts most common differential or LVCMOS input signals. The Si53326 and Si53328 accept only single-ended
LVCMOS inputs. These devices are available in multiple configurations customized for the end application (refer to 1. Ordering Guide
for more details on configurations).
2.1 Universal, Any-Format Input Termination (Si53320/21/22/23/25/27)
The universal input stage enables simple interfacing to a wide variety of clock formats, including LVPECL, low-power LVPECL,
LVCMOS, LVDS, HCSL, and CML. The tables below summarize the various ac- and dc-coupling options supported by the device.
For the best high-speed performance, the use of differential formats is recommended. For both single-ended and differential input
clocks, the fastest possible slew rate is recommended since low slew rates can increase the noise floor and degrade jitter performance.
Though not required, a minimum slew rate of 0.75 V/ns is recommended for differential formats and 1.0 V/ns for single-ended formats.
See “AN766: Understanding and Optimizing Clock Buffer’s Additive Jitter Performance” for more information.
