DESCRIPTION
The ETC5064 (µ-law), ETC5067 (A-law) are mono-
lithic PCM CODEC/FILTERS utilizing the A/D and
D/A conversion architectureshown in the Block Dia-
grams and a serial PCM interface. The devices are
fabricated using double-poly CMOS process.
Similar to the ETC505X family, these devices fea-
ture an additional Receive Power Amplifier to pro-
vide push-pull balanced output drive capability. The
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.
Also included is an Analog Loopback switch and
TSX output.
