DESCRIPTION

• DC-to > 3.2Gbps data rate throughput

• < 620ps In-to-Out t

The SY89546U is a precision, high-speed 4:1 differential

multiplexer that provides two copies of the selected input.

The high speed LVDS (350mV) compatible outputs with a

guaranteed throughput of up to 3.2Gbps over temperature

and voltage.

• < 150ps t /t

r f

Unique input isolation design minimizes crosstalk

Ultra-low jitter design:

• < 1ps

random jitter

RMS

The SY89546U differential inputs include Micrel’s unique,

3-pin internal termination design that allows access to the

• < 10ps deterministic jitter

• < 10ps total jitter (clock)

termination network through a V pin. This feature allows

• < 0.7ps

crosstalk-induced jitter

RMS

the device to easily interface to different logic standards,

both AC- and DC-coupled without external resistor-bias and

termination networks. The result is a clean, stub-free, low

jitter interface solution.

Internal input termination

Unique input termination and V pin accepts DC-

coupled and AC-coupled inputs (LVDS, LVPECL,

CML)

The SY89546U operates from a single 2.5V supply, and

is guaranteed over the full industrial temperature range

(–40°C to +85°C). For applications that require a 3.3V supply,

consider the SY89547L. Or, for applications that only require

one differential output, consider the SY89544U or SY89545L.

350mV LVDS output swing

Power supply 2.5V ±5%

–40°C to +85°C temperature range

Available in 32-pin (5mm x 5mm) MLF package

The SY89546U is part of Micrel’s Precision Edge product

family.
