Postamplifier has designs on fibre optic receivers

Device is easy to use in a wide variety of applications and datarates and meets the industry's most stringent jitter requirements.

Micrel has launched the SY88973BL, a low-power limiting postamplifier that is designed for use in fibre optic receivers; specifically, it is ideal for 1.25 and 2.5Gbit/s Gigabit Ethernet, 1.062Mbit/s and 2.125Gbit/s Fibre Channel, gigabit interface convertor (GBIC), small form factor (SFF) and SFP transceivers, parallel 10G Ethernet, high-gain line drivers and line receivers in both the telecomms/datacomms and optical transceiver markets.

The SY88973BL is another product in Micrel's wide and diverse family of postamplifiers.

It is currently available in volume quantities and is priced at US $3.31 for 1000-unit quantities.

A free evaluation board is also available.

"Micrel's postamplifier family has received wide customer acceptance in part because the entire line offers universally interchangeable parts", says Thomas S Wong, Vice President High Bandwidth Products, Micrel.

"Like the rest of the post amp family, our new device is also easy to use in a wide variety of applications and datarates and meets the industry's most stringent jitter requirements".

The SY88973BL incorporates a loss-of-signal (LOS), open-collector TTL output with an external 4.75 to 10kohm pull-up resistor.

This IC offers multirate capability from 622Mbit/s up to 3.2Gbit/s operation.

It also features internal 50ohm data input and low-noise 50ohm CML data output.

The SY88973BL has chatter-free OC-TTL LOS output with programmable LOS sensitivity using a single external resistor.

Available in a tiny 3 x 3mm 16-pin MLF package, the device operates from a single +3.3V +/-10% power supply, over an industrial temperature range of -40 to +85C.
