A 3.3 V DC power supply must be applied at pins 2 and 6. A recommended power supply
filter network is given in the termination scheme. Locate power supply filtering directly at
the transceiver power supply pins. Proper power supply filtering is essential for good EMI
performance.
TD+ / TD–
Transmitter data LVPECL level inputs. For V23818-C18-L4x terminated and AC coupled
internally. For V23818-C18-L3x/L436 use termination and coupling as shown in the
termination scheme.
RD– / RD+
Receiver data LVPECL level outputs. For V23818-C18-L4x biased and AC coupled
internally. For V23818-C18-L3x/L436 use termination and coupling as shown in the
termination scheme.

A logical LVTTL high input will disable the laser. To enable the laser, an LVTTL low input
must be applied. Leave pin unconnected if feature not required.
SD
LVTTL output for V23818-C18-L4x. LVPECL output for V23818-C18-L3x/L436. A logical
high output indicates normal optical input levels to the receiver. Low optical input levels
at the receiver result in a low output. Signal Detect can be used to determine a definite
optical link failure; break in fiber, unplugging of a connector, faulty laser source. However
it is not a detection of a bad link due to data-related errors.
MS
Mounting studs are provided for transceiver mechanical attachment to the circuit board.
They also provide an optional connection of the transceiver to the equipment chassis
ground. The holes in the circuit board must be tied to chassis ground.
HL
Housing leads are provided for additional signal grounding. The holes in the circuit board
must be included and tied to signal ground.

Description
Description
This data sheet describes the Infineon single mode ATM transceiver, which complies
with the ATM Forum’s Network Compatible ATM for Local Network Applications
document and ANSI’s Broadband ISDN - Customer Installation Interfaces, Physical
Media Dependent Specification, T1E1.2, compliant to SONET OC-3, IR-1 (Telcordia
GR-253-CORE) and SDH STM-1/S-1.1 (ITU-T G.957).
This transceiver is also suitable for multirate applications. The performance at lower
datarates may vary from application to application and is link dependent. Refer to
Infineon Application Note 97 for more information.
ATM was developed to facilitate solutions in multimedia applications and real time
transmission. The data rate is scalable, and the ATM protocol is the basis of the
broadband public networks being standardized in the International Telecommunications
Union (ITU), the former International Telegraph and Telephone Consultative Committee
(CCITT). ATM can also be used in local private applications.
The Infineon single mode ATM transceiver is a single unit comprised of a transmitter, a
receiver, and an LC receptacle. This design frees the customer from many alignment
and PC board layout concerns. The module is designed for low cost LAN and WAN
applications. It can be used as the network end device interface in workstations, servers,
and storage devices, and in a broad range of network devices such as bridges, routers,
and intelligent hubs, as well as local and wide area ATM switches.
This transceiver operates at up to 155.520 Mbit/s from a single power supply (+3.3 V).
The full differential data inputs and outputs are LVPECL compatible.
