roduct(s) DESCRIPTION

te P The ETC5064 (µ-law), ETC5067 (A-law) are mono-

lithic PCM CODEC/FILTERS utilizing the A/D and

le D/A conversion architecture shown in the Block Dia-

o grams and a serial PCM interface. The devices are

sfabricated using double-poly CMOS process.

ObSimilar to the ETC505X family, these devices fea-

ture an additional Receive Power Amplifier to pro-

receive gain can be adjusted by means of two ex-

ternal resistors for an output level of up to ± 6.6 V

across a balanced 600Ω load.
