San Jose, Calif.Micrel Inc. launched the SY88973BL, a low-power limiting post amplifier that is designed for use in fiber optic receivers.
The SY88973BL is well-suited for 1.25-Gbits/s and 2.5-Gbits/s Gigabit Ethernet, 1.062-Mbits/s and 2.125- Gbits/s Fibre Channel, Gigabit interface converter (GBIC), Small Form Factor (SFF) and SFP transceivers, parallel 10G Ethernet, high-gain line drivers and line receivers in both the telecom/datacom and optical transceiver markets.
The SY88973BL incorporates a loss-of-signal (LOS), open-collector TTL output with an external 4.75k ohm to 10k ohm pull-up resistor. This IC offers multi-rate capability from 622-Mbits/s up to 3.2-Gbits/s operation.
It also features internal 50-ohm data input and low-noise 50-ohm 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 3mm x 3mm 16-pin MLF(R) package, the device operates from a single +3.3V plus or minus 10% power supply, over an industrial temperature range of -40°C to +85°C.
Pricing: $3.31 for 1,000-unit quantities.
Availability: Volume quantities; a free evaluation board is also available.
