SY89473U

Precision LVPECL 2:1 Multiplexer with 1:2

Fanout and Internal Termination

General Description

The SY89473U is a 2.5V/3.3V precision, high-speed 2:1

differential MUX capable of processing clocks up to

2.5GHz and data up to 2.5Gbps.

Precision Edge

The differential input includes Micrel’s unique, 3-pin

input termination architecture that directly interfaces to

any differential signal (AC- or DC-coupled) as small as

100mV (200mV_PP) without any level shifting or

termination resistor networks in the signal path. The

output is 800mV, 100K-compatible, LVPECL with fast

rise/fall times guaranteed to be less than 190ps.

Features

• Selects between two input channels and provides two

copies of the selected output

• Guaranteed AC performance over temperature and

supply voltage:

- DC to 2.5Gbps data throughput

- DC to 2.5GHz f_MAX(clock)

- <500ps In-to-Out t_pd

- <190ps t_r/t_f

The SY89473U operates from a 2.5V ±5% or 3.3V

±10% supply and is guaranteed over the full industrial

temperature range of –40°C to +85°C. The SY89473U is

part of Micrel’s high-speed, Precision Edge^®product

line. For multiple-clock switchover solutions, please refer

to the SY89840–SY89843U family.

- <20ps Output-to-output skew

• Unique patented input isolation design minimizes

crosstalk

All support documentation can be found on Micrel’s web

site at: www.micrel.com.

• Ultra-low Jitter Design:

- <1ps_RMSrandom jitter

- <1ps_RMScycle-to-cycle jitter

- <10ps_PPtotal jitter (clock)

- <0.7ps_RMScrosstalk induced jitter
