SY58621L

Precision 3.2Gbps CML/LVPECL Backplane

Transceiver with Integrated Loopback

General Description

The SY58621L is a low jitter, high-speed transceiver

with a variable swing LVPECL transmitter buffer and a

CML high-gain receiver optimized for precision telecom

and enterprise server transmission line and backplane

data management. The SY58621L distributes data to

3.2Gbps guaranteed over temperature and voltage.

Precision Edge^®

Features

• Guaranteed AC performance over temperature and

voltage:

- Maximum Throughput 3.2Gbps

- <160ps t_r/t_ftime

• Transmitter

The SY58621L transmitter differential input includes

Micrel’s unique, patented 3-pin input termination

architecture that directly interfaces to any (AC- or DC-

coupled) differential signal as small as 100mV

(200mV_PP) without any termination resistor network in

the signal path. The receiver differential input is

optimized to interface directly to AC-coupled signals as

small as 10mV (20mV_PP). The receiver output is 50_

source-terminated CML and the transmitter output is

variable swing 80mV to 800mV LVPECL with extremely

fast rise/fall time.

- Patented input termination directly interfaces to AC-

or DC-coupled differential inputs

- Variable swing LVPECL output

• Receiver

- 32dB high-gain Input

- Internal 50Ω input termination

- Accepts AC-coupled input signals as small as 10mV

(20mv_PP)

- 400mV (800mV_PP) differential CML output swing

• Loss-of-Signal (LOS)

- High-gain, TTL-compatible LOS output with internal

4.75kΩ pull-up

To support remote self-testing, the SY58621L features a

high-speed loopback test mode. The input control signal

LOOPBACK enables an internal loopback path from the

transmitter input to the receiver output.

- Programmable LOS level set

• Ultra-low jitter design

- <5ps_RMSrandom jitter

• Patent-pending MUX isolates the receiver and the

transmitter channels minimizing on crosstalk

• Selectable loopback diagnostic mode

• Output enables on transmitter and receiver outputs

• Power supply +3.3V ±10%

The SY58621L operates from a 3.3V ±10% supply and

is guaranteed over the full industrial temperature range

of –40°C to +85°C. The SY58621L is part of Micrel’s

high-speed, Precision Edge^®product line. For

applications that requires a CML receiver and

transmitter, consider the SY58620L.

All support documentation can be found on Micrel’s web

site at: www.micrel.com.

• Industrial temperature range -40°C to +85°C

• Available in 24-pin (4mm x 4mm) MLF™
