SY89297U

2.5/3.3V, 3.2Gbps Precision CML

Dual-Channel Programmable Delay

General Description

The SY89297U is a DC-3.2Gbps programmable, two-

channel delay line. Each channel has a delay range from

2ns to 7ns (5ns delta delay) in programmable increments

as small as 5ps. The delay step is extremely linear and

monotonic over the entire programming range, with 15ps

INL over temperature and voltage.

Precision Edge^®

Features

• Dual-channel, programmable delay line

• Serial programming interface (SDATA, SCLK, SLOAD)

• Guaranteed AC performance over temperature and

The delay varies in discrete steps based on a serial control

word provided by the 3-pin serial control (SDATA, SCLK,

and SLOAD). The control word for each channel is 10-bits.

Both channels are programmed through a common serial

interface. For increased delay, multiple SY89297U delay

lines can be cascaded together.

voltage:

– > 3.2Gbps/1.6GHz f_MAX

• Programming Accuracy:

– Linearity: −15ps to +15ps INL

– Monotonic: −5ps to +25ps

The SY89297U provides two independent 3.2Gbps delay

lines in an ultra-small 4mm x 4mm, 24-pin QFN package.

For other delay line solutions, consider the SY89295U and

SY89296U single-channel delay lines. Evaluation boards

are available for all these parts.

– Resolution: 5ps programming increments

• Low-jitter design: 1ps_RMStypical random jitter

• Programmable delay range: 5ns delay range

• Cascade capability for increased delay

Datasheets and support documentation can be found on

Micrel’s web site at: www.micrel.com.

• Flexible voltage operation:

– V_CC= 2.5V ± 5% or 3.3V ± 10%

• Industrial temperature range: −40°C to +85°C

• Available in 24-pin (4mm x 4mm) QFN

Applications

• Clock de-skewing

• Timing adjustments

• Aperture centering

• System calibration

Markets

• Automated test equipment

• Digital radio and video broadcasting

• Closed caption encoders/decoders

• Test and measurement
