19 / 29 page ![]() Aeroflex Circuit Technology SCD7005 REV B 8/2/01 Plainview NY (516) 694-6700 19 Pin # Signal Name Signal Description 16 VDD Digital Supply Voltage 87 VDD Digital Supply Voltage 2 GND Digital Grounds 34 N/C / SERR N/C - ACT7005, SERR on ACT7006 - Subsystem Error. When low sets the SSF Bit in the RT’s return status word. 80 GND Digital Grounds 38 VccL (A) Transceiver A +5VDC Supply Voltage 44 GND (A) Digital Ground A 43 GND (A) Analog Ground A 39 N/C No Connection 41 GND (A) Transceiver A Output Ground 53 VccL (B) Transceiver B +5VDC Supply Voltage 47 GND (B) Digital Ground B 48 GND (B) Analog Ground B 52 N/C No Connection 50 GND (B) Transceiver B Output Ground 81 AD0 Address Inputs AD0 - LSB AD3 - MSB These four signals provide the address codes that control the operation of the interface. 82 AD1 83 AD2 84 AD3 85 A10 IN A10 IN is the address input to the internal RAM. 86 A10 OUT A10 OUT buffered TX/RX bit when tied to A10 IN segregates the 2k by 16 RAM into two 1k by 16 blocks of memory: one for Receive, the other for Transmit Data. 23 BCSTEN Broadcast Enable. When low, the recognition of Broadcast Command is prevented on the specified bus. 25 BIT DECODE Built-ln Test Decode. When held low, prevents resetting TXTO Bit, HSFAIL Bit, and LTFAIL Bit in the Bit Word (as well as TF and SSF Bits in the Status Word) upon receipt of a Transmit Bit Word Mode Command. 59 BUFF EF Buffer Empty Flag - goes low when the output FIFO Buffer is empty. Will transition to the high state when the first word appears in the Buffer. Table 11 – Pin Number Description |
