TP3069``Enhanced'' Serial Interface
CMOS CODEC/Filter COMBOÉ
General Description
The TP3069 (A-law) is a monolithic PCM CODEC/Filter utilizing
the A/D and D/A conversion architecture shown in
Figure 1 , and a serial PCM interface. The device is fabricated
using National's advanced double-poly CMOS process
(microCMOS).
Similar to the TP305X family, this device features 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 g6.6V across a balanced 600X load.
Also included is an Analog Loopback switch and a TSX output.
Note: See also AN-370, ``Techniques for Designing with CODEC/Filter
COMBO Circuits.''
