General Description
The TP3064 (m-law) and TP3067 (A-law)are monolithic
PCM CODEC/Filters utilizingthe A/Dand D/A conversion
architecture shownin Figure1,anda serial PCM interface.
The devicesare fabricated using National’s advanced dou-
ble-poly CMOS process (microCMOS).
Similartothe TP305X family, these devicesfeaturean addi-
tional Receive Power Amplifierto provide push-pull bal-
anced output drive capability.The receive gaincanbead-
justedby meansoftwo external resistorsforan output levelupto g6.6V acrossa balanced 600X load.
Also includedisan Analog Loopback switchandaTSXout-
put.
