SY89113U

2.5V Low Jitter, Low Skew 1:12 LVDS

Fanout Buffer with 2:1 Input MUX and

Internal Termination

General Description

The SY89113U is a 2.5V low jitter, low skew, 1:12

LVDS fanout buffer optimized for precision telecom

and enterprise server distribution applications. The

input includes a 2:1 MUX for clock switchover

applications. Unlike other multiplexers, this input

includes a unique isolation design that minimizes

channel-to-channel

crosstalk.

The

SY89113U

distributes clock frequencies from DC to >1GHz

guaranteed over temperature and voltage. The

SY89113U incorporates a synchronous output enable

(EN) so that the outputs will only be enabled/disabled

when they are already in the LOW state.

CLK0 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

) without any level shifting or

termination resistor networks in the signal path.

CLK1 differential input includes a new version of

Micrel's unique, Any-Input architecture that directly

interfaces with single-ended TTL/CMOS logic

(including 3.3V logic), single-ended LVPECL,

differential (AC- or DC-coupled) LVDS, HSTL, CML,

and LVPECL logic levels as small as 200mV

(400mV

). CLK1 input requires external termination.

LVDS output swing 325mV into 100Ω with extremely

fast rise/fall time guaranteed to be less than 250ps.

The SY89113U operates from a 2.5V±5% supply and

is guaranteed over the full industrial temperature

range of -40°C to +85°C. The SY89113U is part of

Micrel's high-speed, Precision Edge product line.
