‘‘Enhanced’’ Serial Interface
CMOS CODEC/Filter COMBO
é
General Description
The TP3064 (
m
-law) and TP3067 (A-law) are monolithic
PCM CODEC/Filters utilizing the A/D and D/A conversion
architecture shown in Figure 1, and a serial PCM interface.
The devices are fabricated using National’s advanced dou-
ble-poly CMOS process (microCMOS).
Similar to the TP305X family, these devices feature an addi-
tional Receive Power Amplifier to provide push-pull bal-
anced output drive capability. The receive gain can be ad-
justed by means of two external resistors for an output level
of up to
g
6.6V across a balanced 600
X
load.
Also included is an Analog Loopback switch and a TS
X
out-
put.
