MP5491GC-0000中文资料美国芯源数据手册PDF规格书

DESCRIPTION

The MP5491 integrates four high-accuracy

current sources for laser diodes (LDs), which

makes this device well-suited for the transmitter

optical subassembly (TOSA) of quad, small

form-factor pluggable (QSFP) optical modules.

The device integrates 6-channel GPO outputs.

These outputs status can be configured via the

I

2C interface.

The MP5491 requires a minimal number of

external components, and it is available in a

space-saving WLCSP-36 (3mmx4.25mm)

package.
