Four Channel 25G / 28G CDR with Integrated TIA

The MATA-37044 includes a high-sensitivity TIA with selectable bandwidth to support legacy data rates, a limiting amplifier and an output driver with programmable output swing and de-emphasis. This amplifier features programmable slice level adjust, LOS threshold and an average photodiode current monitor (RSSI). The MATA-37044 is available in a 3 mm x 2 mm die supplied in waffle packs, whole wafers or quartered wafers.
