SY897132L
1.5Gbps Link Replicator for Fibre Channel,
Gigabit Ethernet, HDTV and SATA
General Description
The SY897132L is a Link Replicator which provides
both serial loop replication as well as serial loopback
control functions. It is high performance and works up
to 1.5Gbps on 3.3V power supplies. The SY897132L is
ideal for Fibre Channel, Gigabit Ethernet, HDTV and
SATA applications. Other applications include
internal/external connection routing in Host Bus
Adaptors as well as hot-pluggable links between switch
cards.
Precision Edge®
Features
• Serial loop replication
• No external components required
• T11 Fibre Channel compliant at 1.0625Gbps
• IEEE802.3z Gigabit Ethernet compliant at 1.25Gbps
• SMPTE-292M compliant at 1.485Gbps
• Operates with 3.3V ±5%
The IN input is sent to both OUT0 and OUT1, which are
enabled when OE0 and OE1 are HIGH and disabled
when they are LOW. When the outputs are disabled,
both differential outputs go HIGH and the buffers are
turned off to save power.
• Industrial temperature range: –40°C to +85°C
• Available in 28-pin TSSOP package
MUX0 controls whether IN or IN1 is sent to OUT0.
Similarly, MUX1 controls whether IN or IN0 is sent to
OUT1. MUX selects whether IN0 or IN1 is sent to OUT.
Applications
• Link Replicator for: Fibre Channel, Gigabit Ethernet,
The SY897132L operates on 3.3V ±5% power supplies
and is guaranteed over the full industrial temperature
range (–40°C to +85°C). The SY897132L is part of
Micrel’s high-speed, Precision Edge® product line.
HDTV and SATA
• For line cards to provide redundant, hot-swappable
links to redundant switch fabric cards
• For host bus adapter boards for routing between
internal and external connectors

Notes:
1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not
implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratings conditions
for extended periods may affect device reliability.
2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
3. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the device's most negative potential on the PCB. ψJB and θJA
values are determined for a four-layer board in still-air number, unless otherwise stated. The circuit is designed to meet the DC specifications
shown in the above table after thermal equilibrium has been established.
4. JEDEC standard multilayer board -2S2P (2 signal, 2 power)

6. Output-to-Output skew is the difference in time between both outputs, receiving data from the same input, for the same temperature, voltage and
transition.
7. Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and no skew at the edges at the
respective inputs.
8. Deterministic jitter is measured at 1.5Gbps with both K28.5 and 223–1 PRBS pattern.

SY897132L
Detailed Description
OEx Output Enable
Input Functionality
The Output Enable (OEx) pins on the SY897132L
provide an option to turn on/off OUT0 and/or OUT1. If
OEx is LOW, the entire output buffer is turned off and
both differential outputs float HIGH. This would
reduce overall ICC by approximately 26mA for each
disabled output pair.
The inputs are typically AC-coupled and are
terminated internally to 1.2V. SY897132L can accept
AC-coupled and DC-coupled LVPECL, CML.
Outputs Termination
The SY897132L are capable of driving differential
transmission lines with either 50Ω or 75Ω impedance.
The outputs are designed to operate with or without
external termination resistors. However, differential
transmission lines should be terminated at the
destination to avoid reflections and noise. See Figure
3 for more details.
Power Supply Bypass
The SY897132L uses separate 3.3V power supplies
for its core circuitry and output buffers. By separating
the power supplies, SY897132L minimizes the impact
of noise coupled onto the power supply by the various
switching outputs. Placing a 0.1µF bypass capacitor
on the VCC pins will provide additional noise isolation.
