TP3064, TP3067 Enhanced Serial Interface CMOS CODEC/Filter COMBO Literature Number: SNAS570 TP3064, TP3067
��Enhanced’’ Serial Interface
CMOS CODEC/Filter COMBOÉ
General Description Features 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 double-poly CMOS process (microCMOS).
Similar to the TP305X family, these devices feature an additional Receive Power Amplifier to provide push-pull balanced output drive capability. The receive gain can be adjusted by means of two external resistors for an output level
of up to g 6.6V across a balanced 600X load.
Also included is an Analog Loopback switch and a TSX output.
