All rights reserved. [1] Explanation of input and output ports: IN: digital input port; all dedicated inputs are TTL tolerant. IN1: digital input port with internal pull-up resistor. I/O10: bidirectional port with 10 ns slew rate. O10: 3-state (in test mode) output port with 10 ns slew rate. APIO: analog input port. VDDCO: analog VDD port (1.8 V). VSSCO: analog VSS port. GND_IO: ground for I/O pads. VCC_IO: VCC for I/O pads (3.3 V). GND_core: ground for core. VCC_core: VCC for core (1.8 V). 7. Interfaces 7.1 Host interface Different types of host busses are supported: • Separate address/data bus with 16-bit data bus (3 different modes) • Multiplexed address/data bus with 16-bit data bus (2 different modes) • Separate address/data bus with 8-bit data bus (1 mode). The host interface type is set via the dedicated pins H_sel and sys_clk. The SAA7893HL has a dedicated interrupt output pin. 7.2 Front-end interface 7.2.1 Data input interface The SAA7893HL supports three different front-end interfaces which are selectable via the host interface: • I2S-bus interface: the front-end interface is in essence an I2S-bus interface and therefore, it has to conform to the I2S-bus specification. • FEC interface DSD_PCM_10 119 O10 2-channel data output DSD_PCM_9 120 O10 2-channel clock or control DSD_PCM_11 121 O10 2-channel data output RESETn 122 IN asynchronous reset; active LOW H_A_sel 123 IN address select H_A[6] 124 IN address bus H_A[5] 125 IN address bus H_A[4] 126 IN address bus H_A[3] 127 IN address bus H_A[2] 128 IN address bus Table 2: Pin description…continued Symbol Pin Type[1] Description |
